Can someone help, i have been having trouble connected with my home universities vpn, for past 15-20days, it is an openvpn connection, so i have been using networkmanager-openvpn to import my config files, and they have worked previously, but for last 15-20 days i get connection timed out, all certificates used are correct, i have tried to connect on cli,

Connection activation failed: The connection attempt timed out

and it suggests to check journalctl logs (nothing erroneous i could find) i am also able to connect with this vpn with my phone (with openvpn official app with same files), and also i am able to connect to proton’s vpns with my laptop, so i guess my device is not completely broken, i have tried to redownload my certificate files, recreating vpn profile, reinstalling networkmanager, nothing worked

    this repeats over and over, i killed it, also i tried to connect with our vpn a year or 2 ago this method, and had same/similar errors even back then, and it only used to worked with network manager

    sorry for editing it heavily, but would love to not be doxxed

      That’s your error. So I think

      data-ciphers AES-128-CBC
      

      In your config should resolve this. Basically there’s some issues with CBC and it’s now off by default.
