This happens because XMPP fails to verify server certificate via TLS

Has started happening because #2 was fixed.

timiimit commented 1 year ago

after further investigation i found out that verification works just fine, its just that the search location is incorrect. for some reason OpenSSL checks //certs (maps to /certs) directory. i'm not sure how to handle this. i will need to google a bit to figure out optimal paths for generic distros. openssl version -d seems to return used directory and on my archlinux it uses /etc/ssl.

timiimit commented 1 year ago

For now i think ill just hard-code the /etc/ssl location. it seems that most distros use either this or /etc/ca-certificates. there is update-ca-trust command (hopefully on all distros) which can help configure /etc/ssl if it does not exist.

Another issue was not being able to open up the friends list. I managed to enable it after looking a bit into linux's calling convention (System V AMD64 ABI), which is more convenient than windows x64 calling convention in some cases.

While hovering over the button that opens friendlist, tooltip still says that current platform is not supported. Since that is part of the menu i will leave it as it is. This will be fixed later when menus get reimplemented.
