Configuration works on Windows but not iOS (iPad 7, iPhone 13mini)

[horo]

My configuration works perfectly fine on a Windows 10 Desktop but if I use it on iOS I cannot open any page on any browser. They all fail with "page unreacheable" after long seconds of loading. In the OpenVPN connect app, everything is green. it seems to say I am connected to the server.

What I just want is all the traffic to go through the VPN server, I do not need the client to be able to access other machines in the VPN intranet.

I almost have no experience with iOS stuffs so a little bit of help troubleshooting would be more than welcome.

Thanks in advance !

EDIT: I tried regenerating all the key/certs with easy-rsa 3 to get rid `tls-cipher "DEFAULT:@SECLEVEL=0"` because I know that Apple is pretty strict with security in general. Now I managed to get rid of `tls-cipher "DEFAULT:@SECLEVEL=0"`and `cipher AES-256-CBC` but it still works on Windows and fails on iOS in the same manner.
