Hey all,

Anyone else running into this with trying to connect that it sees the server, but gives an Unknown connection error?

Ok upon further investigation I figured out the issue, which was on a fresh firefox install I also installed the most recent Bitwarden extension, which is incompatible with our version of the server, which I am on 202 which runs 2026.1.1 and needs that same version extension. So I resolved this but we are out of sync with the most recent firefox extension and also server.
