Play Store will not download when VPN is connected - Samsung Galaxy S9+ Questions & Answers

So I can't seem to find a straight answer on this because most of the results that come up in searching have to do with geolocking due to using VPNs with foreign endpoints, and that is not the issue here. I have a VPN server at home, and I keep my phone connected to it at all times to funnel traffic through my pi-hole (phone is not rooted, so no other reliable adblocker can be installed). Play store refuses to download or update anything unless I disconnect the VPN. I originally thought it was the pi-hole itself breaking something, but if I connect to home wifi (runs through the same pi-hole) it works just fine (no it is not set to wifi only). If I just disconnect the VPN, it works fine over LTE. I have true unlimited, and rarely use wifi, so I never turn it on. I tried IFTTT to turn it on only at home but it never works right.. More often than not, it doesn't turn it off when I leave - which causes it to try to connect to random saved hotspots as I drive through town, or the one at work which has crappy coverage, which interrupts my streaming radio.
Is there some hidden setting or tweak I can do to make it work properly and do automatic updates? As I said, the VPN is connected at all times, and I don't remember to check for updates regularly, so it is not uncommon to find dozens of apps that haven't installed updates in a month or more. I DO get notifications of OTA FW updates from the carrier each month or so.
It's a SM-G965U1 (CSpire model on a local mom and pop carrier) if it matters,

GMail sync only with home wi-fi

Hi
I'm not sure if it's Android or Transformer prime thing.
My google data (gmail, gcal) syncs properly and immediate when i'm @home with my wifi network, but refuses to automatically sync at the office wi-fi network.
The office network is freely available to the device, i can browse the net without any problems.
Can figure it out why the sync doesn't work.
I have noticed the same issue on mine except my home network sometimes has the issue too. I have resolve it by disabling the sync and then enabling it again. This method works for a little while then it seems to go into the no new notification mode. I have to manually refresh in gmail to get my new mail to show up. It is annoying. I even send test emails to both my phone and tablet, but it will not ccome through until it feels like it or unless I manually update. My xoom does not do that.
I have a sort of similar thing. All I know is that I'll be delivering pizzas while tethered. As soon as I get home, and turn off the tethering, my tablet connects to the home WiFi and gets one or more notification noises as it if wasn't syncing the same way when tethered. The oddity is that it doesn't know I'm on a mobile connection so it isn't trying to save bandwidth. I suspect there is something in the security or ports that makes it's connections to the home network different than when tethering, or when you are at work.
I can't speak to the issue regarding tethering, but for those of you having issues at the office, this is most likely due to firewall rules. I work for a cybersecurity software company, and have been fighting for them to address this as both my phone and prime suffer from the same thing.
If you have a good relationship with your IT/Corporate security people, try bringing it up with them.

do you know if google sync services uses other than 80/443 port numbers?
Not only did I notice this same thing happening I also noticed emails I had are disappearing when not on home network and Wi-Fi tethering with my phone this is weird...... they disappear from my gmail application......

[Q] phone gets stuck on old wifi networks

Okay, having a really weird issue here. My work just gave us all brand new Motorola Admiral handsets to replace our old Nextel Blackberries. My phone works fine except that it keeps getting stuck on old wifi networks. As an example, we have a couple of different SSIDs in use at work, depending on the site. If I have it connected to SSID-A and then go to a second site with a different SSID, it still shows me as connected to SSID-A. Even between sites it shows that. Now I am at home and it still shows SSID-A.
Of course the phone thinks it's connected to wi-fi so the 3g connection doesn't work at all and it isn't connecting to my home wi-fi. If I disable wi-fi and then turn it back on then it will connect but I should have to manually turn it off and on every time I go out of range of an AP. No luck with Google so I figure I would ask here.

Can I get my device to auto-connect to WiFi without internet?

Hi everyone,
I own a Nexus 5 and I am running stock firmware, Android 6.0 MRA58K, unrooted and bootloader locked. I use this device at work and frequently connect to a WiFi LAN that has no internet connection (by design -- I use it to talk to other devices on the network). In older software versions (I believe back in the KitKat days if I recall), I could simply turn on the WiFi slider on my phone, and it would automatically connect to the network, and I could immediately start talking to the devices I need to (this was excellent!). Then when Lollipop first rolled around, it would still connect to the network automatically, but it would realize that there's no internet connection, so it would then prioritize the Cellular Data network, preventing me from communicating with my network devices. So I had to do an extra step by disabling my data connection, then things would work properly again. (Of course, this also meant that when I wanted to jump off the Wi-Fi, I would need to re-enable Cellular Data.)
Nowadays, Android seems to remember that my WiFi network doesn't have an internet connection, so it never joins it by default (very frustrating!). So every time I want to jump on the network, I need to turn on WiFi, then manually select the network to join, then go into the Data section and disable cellular Data, and then things would be working fine. Of course, if I ever walked away from the Wi-Fi range and then came back, I would again need to manually select the network.
And now with this lastest Marshmallow update, a new Notification pops up every time I join the Network that says:
"Wi-Fi has no Internet Access. Touch for options." When touched it says, "This network has no Internet access. Stay connected? Yes/No" There's also a checkbox that says, "Don't ask again for this network". Every time I check that box, and say YES to stay connected. And yet each and every time I connect to the network, this notification appears again! (The checkbox seems to do nothing). I've looked at the Advanced options in the Wi-Fi settings, and nothing there seems to help.
So my question is, is there a way for me to go back to the "good 'ole days", where I can get my phone to automatically join this WiFi network, and still prioritize it over cellular data?
If need be, I'm perfectly fine with rooting/unlocking my phone, if I need to install some custom firmware or whatever.
Thanks in advance for any suggestions you might have!

Question on wifi calling country authentication

I travel a lot for work from the US to China. In the past, I've utilized wi-fi calling on my LG G4 on Sprint for texts / voice capabilities. Sprint doesn't allow wifi calling in China, but there was an easy work around: I would VPN to a US based location (needed to access anything google), connect to a wifi network, turn on global roaming and then use a fake GPS locator app set to somewhere in the US. When used in tandem, I was able to to connect to wifi calling just as if I was in the states. I've done this successfully for the past six trips to China over the past year, but my most recent trip to China this method no longer worked.
When trying to authenticate wifi calling, it times out and gives an notification error in the status bar "wifi calling is not allowed in this country". I believe Sprint does its locating via Google (one of the main reasons wifi calling doesn't work here) but that shouldn't be an issue if I have VPN access and can utilize the suite of my other Gapps. During the timeout, sometimes I get a redirect to the following site:
http://clients3.google.com/generate_204. Does anyone know what may have changed in the past two months in regards to this verification?
Once I left China, I was able to successfully connect to wifi calling in both Hong Kong and back in the US without any issue. I believe the root of the issue is somehow the location verification has changed and I can't figure out how to properly spoof my location while in China. I've tried different fake GPS apps (need to turn on mock locations), so that's not the issue, but something to do with the network verification. I know the VPN is working because I can access all my other google apps.
Thanks for all your input!

I'm connecting to wifi to my GL. Inet mobile router which is connected to a US private VPN (own server). I don't use VPN on the phone, nor do I use a location spoofer.
Always worked for me. Phone thinks its in the USA.
Apologies for necroposting, but how do you get around your home carrier trying to connect to a tower in the other country while roaming?
Also, what app do you spoof GPS? I'm a bit reluctant to download a random GPS app off the playstore.

S9+ showing "connected to WLAN, no internet"

So, I got my S9+ (international version, DUOS, 256 GB) last week from the Samsung store. I am on stock ROM (and will stay as long as my warranty lasts or someone finds a way to root with Knox 0x0, which I am not expecting).
At home, I have a WLAN Mesh (AVM Fritz!Box 6590 Cable, 2x AVM Fritz! 1750E Repeater on a wired connection), everything working great with any device.
Except my S9+. It connects and everything is fine, at some point - especially when using it for e.g. streaming Netflix or so - it will stay connected to the WLAN but will say "no internet access". Switching WLAN on and off fixes the issue until it happens the next time (minutes to hours later). I have no special settings, no neighbouring networks which would interfere. I have 2,4 and 5 GHz active and automatic channel selection. All other devices in my home work with no problems. I have found similar issues froim users on other Samsung phones (S6/7/8 series (my former S5 on Resurrection Remix Oreo does not show t his behaviour)), but no answers that worked (like forget the network, reboot and reenter credentials).
Quite annoying, anyone knows a fix? Big THANKS in advance.
No one experiencing the same thing or havin any ideas?
I have had the same issue in the beginning with the phone. I have a router with a cisco switch connected to it. The standard router's wifi wasn't sufficient in coverage through my house. I got hold of a cisco AP and connected it to the switch and disabled the wifi on the router. That's when my issue started. Fiddled around trying various options, but the one that worked for me was to tell the phone to forget my network, restart the phone and then "setup" the wifi on the phone again(password for wifi needed to be entered as it sees the network as a new one) Haven't had the issue after that. I did notice at my office that even though the wifi conection is good, that if it goes below a certain percentage, the mobile data will kick in, although I have that option switched off. I also picked up that if your line connection's speed goes very low for whatever reason, the same problem appears again that the phone assumes there is no internet
Thanks, this is what I've read from other threads (with S7, S8), too. But this didn't work for me. My repeaters get ther signal through LAN cable and I have a fast connection, coverage all over my house and garden. I really do not have an idea on what to try...
