No internet connection with specific apps - Galaxy S II Q&A, Help & Troubleshooting

Hello xda-Developers, got a weird bug incoming (once again):
I am on NeatROM 5.9 (4.1.2 JellyBean) with Apolo Regular Kernel and just wanted to download AdFree via Dolphin Browser, but no matter what website I want to visit; it always tells me that I have got a connection error. After I downloaded AdFree via my PC and wanted to check the Host files, it got stuck there as it wouldn't do anything in the loading screen. Other apps like AdAway got the same error (not wanting to download host files), but apps like Google Play, Facebook, WhatsApp or others work fine. This problems no matter if I am connected with Wi-Fi or with Mobile Data.
My question is: How can I get back my internet connection?
EDIT: Found the problem, DroidWall was blocking these apps from connecting. Just activated then deactivated the firewall and everything worked out

[Q] [Help] Can't establish reliable data connection

Hi,
I am on BB 71, Fxp kernal, MiUI black editionHD rom and now I am facing this error of not able to log into the google ac form my phone.
I am able to browse the data on a browser but not through any applications like the XDA nor market etc... I tried all the tricks from this forum like a complete fresh install from the BaseBand till the application, also through youtube login but none of these seems to work out.
I have also tried the MIUI data drop patch, All these still prove to be useless as I am unable to login to the google account.
Anyone with the same experience??

[Solved] Saferoot, googleplay

Hello there users of xda,
After I installed saferoot I've notice that my google play stopped working via wifi connection but works on my 4g connection. No connection to google play via wifi, also while connected via wifi I've tried to download apps via google play on the computer. A notification pops up on my phone telling me the download failed. On the other hand if I am connected via 4g, google play on the s4 works just fine. I am a noob here.
I don't have much data to run on as I have already used half of it on pandora while going to work and returning from work (2gb data plan).
phone: Galaxy S4
Model: SCH i545 (if you can't tell already it's verizon)
Android Version: 4.3
Build: mk2
Root: Yes=saferoot + safestrap​
Never mind, I've solved the problem. The problem occurred after I've uninstalled abp (adblockpro). When I installed adblockpro, my proxy setting was changed on my s4, all I had to do was change the proxy setting back to the default settings.

WiFi connection but no internet.

I recently restored my old inactive CMDA Sprint Evo 3D back to stock 2.17.
After booting it up, I connected to WiFi and successfully obtained an IP and connected.
I am restored to fully stock with S-Off with a Locked bootloader.
When I try to open the market or web browser I don't have internet.
The web browser says "Web page not available".
I am connected to the WiFi network on other phones and this computer, so internet is working.
Tried multiple PG86 .zip restores and RUU .exe restores.
Even wiped /Data, /System, /Cache and then restored using the PG86 .zip, so there were no files that might be left behind causing issues.
Can anyone help me fix my WiFi issue?
More info please
Thank you for the reply but that's really all that I have.
It's a Sprint CDMA Evo 3D currently restored to stock using RUU_Shooter_ICS_35_S_Sprint_WWE_2.89.651.2_Radio_1.09.00.0706__NV_NV_SPCS_1.43_release_271101_signed.exe.
During setup, I connect to my WiFi and it connects successfully and shows full WiFi bars in the notification bar. I also tried skipping wifi during setup then connecting normally from the wifi in the settings menu.
When I try to use the internet, nothing will connect. Browser wont load a page and play store wont connect, wont even log into my google account.
Feels like the phone is blocking internet access, like though a firewall or hosts, but it doesn't have any additional apps installed and the hosts file is original stock since my /system partition is locked from the restore.
I just did the HTC official bootloader unlock, thinking the wire trick unlock may have been causing it, but it didn't help.
What other info would be useful?
EDIT: Just flashed CyanogenMod 11 with Android 4.4.4 and WiFi is working. No idea why stock won't work but AOSP does.

[PROBLEM] Cellular data is working but not working, WEIRD!!!

Hello guys, what's up?
This is SO weird but here I am facing a problem in my Galaxy s2, and need your advice.
The whole thing is my Cellular data (Internet of Sim Card) is not working on Browsers(tried stock one+Firefox)+Google products and some other apps, but works on Clash of Clans and aptoide app store. And it works with EVERYTHING when I'm using it as a hotspot, like now I'm connected to my phone internet via wifi and there is literally no problem at all, I even have an android emulator running in background without any problems with Google Play and other stuff so it's basically a problem related to my phone.
Also WiFi itself works fine on phone, when I connect to my cousin wifi home connection, everything works like charm but when I switch back to mobile data....
I don't know what's going on... It suddenly happened on my phone and I didn't install any apps or change the system files.
Things I've done:
1- Wiped /data + /system and factory reset for like a billion time
2- Changed my rom with clean install (Even switched to older CM13 versions to make sure there is nothing wrong with my new roms)
3- Removed battery + tried all of the basic troubleshooting stuff
4- Checked the host file in /System/Etc and there was just: " 127.0.0.1 localhost "
Btw when I open the browser (CM13 stock one), this the exact error I'm getting:
ERR_CONNECTION_RESET
What should I do? :crying:
Oops. sorry I forgot to mention, everything works fine when I use VPN. Somehow VPN+Clash of Clans and Aptoide appstore all work but Play store and everything else aren't, seriously what's wrong?
I just removed the host file now and rebooted but it didn't solve the issue
I fixed it!!! Thread needs to be closed
@HutchGuy how did you fix it?

Playstore/Youtube sometimes no connection ??

Hey there,
so i just got my SM-P605 with a custom rom from here to Android 7.1.
When it was stock stock everything worked fine but I wanted 7!
I flashed a 5.1.1 Stock Rom(needed the bootloader for twrp) wich I downloaded elswhere and Problems started, at the new setup I wasn't able to login to my google Account and skipped it, my connection to Wifi was stable and the browsers all worked fine except YT and Playstore etc. basicly everything with google.
Then I installed mentioned 7.1 rom and the same problems, I tried deleting installing Play Services, Play store, delete various Caches aswell in TWRP and Time settings set right.
The thing is I get acces to all perks from time to time wich is.... magic ? it is like 15min not possible then 2min everything works just fine ???
When I go to a different Wifi everything works fine 100% of the time no Problems at all.
But the mentioned Problem wifi has 3 other Tablets connected and 2 Smartphones with no Problem at all.
The not working Wifi is via the Win10 Hotspot from my PC and the stable one from my Dorm wich I dont wanna use cause it is very very unstable and slow.... 300-700kb/s compared to 12mb/s from the PC.
I raed alot about People not having a connection on Play store but they all had it permanently and not like mine
Anyone has a guess ?
