I made app that access php files on this server.
It worked normally and it stopped working before few days,on android versions lower than 5.0.
I have searched a bit and some people suggested that it might be something wtih TLS protocol (lower android version can access only lower version of TLS ( TLSv1.1))
So have you guys changed something or you have any idea how i can switch back or fix this?
EDIT: i have logs if soemone want to see,most of them says info_callback: ignored or SSL connection error
