I am using ‘Bluestacks’ software emulator for some time now. And it was a perfect emulator to test any android applications or games on PC. Recently it stopped working and showed me an error message “can’t establish a reliable data connection to the server”.This error message came when i tried to access PlayStore directly from the screen”. And it's now not letting me sync my Google account as well. When I try to access Playstore directly from bluestacks browser, it's now showing me “certificate is not trusted” error.
I tried reinstalling and reinstalling older versions, clearing the cache of Playstore services in app settings, downloaded Youtube Apk and installed directly. But nothing worked so far. So I decided to close it for a while since I couldn't find any other fixes online. Recently I opened it again to search for and fix the problem. And guess what? I found it!
The “Antivirus Software apparently causes this”. I am using ESET Smart Security. I tried disabling antivirus before. But simply disabling won’t work. You need to go to “Setup-> Enter advanced setup.
And unmark option “Enable HTTP checking”.
Note: - If you are using any other antivirus software follow the corresponding method to disable HTTP checking. And that’s it. I can now sync my google account and connect to the Playstore. The network problem now fixed.
Update - Fix 2
From an anonymous user comment
This fix is also working. You need to exclude Bluestacks from HTTP filtering where it says exception on your antivirus software.
On my Antivirus software, ESET this is what it looks
Windows Bit Defender Test *** Needs Confirmation***
I'm not verified this - on karspersky the settings are located in the lower left part of the window of the antivirus home screen. For more info where is the setting located check here
You can find additional settings from there
