Why can't foreign apps connect to the internet?

[AC Question]

Foreign apps can't connect to internet

I've downloaded some apps which are unavailable in my country using .apk file download, they used function properly before but suddenly it stopped working and won't connect to the internet. It says 'unknown error occured'. Please help me... Thank you very much

Welcome to the forums. You are probably being blocked at the server level. Probably not much you can do.

Re: Foreign apps can't connect to internet

but it used to work normally before...I didn't change anything in my settings or whatever. I also tried uninstalling and reinstalling it, and even tried installing the older version but it didn't work either. Why do these things suddenly happen? And how do I prevent this from happening to my other apps? Thank you for your reply
