Please tell us a bit about the networking setup here. Is cockpit installed/running on your own PC or on some remote machine? Do you have a direct connection to that, or is there a proxy in between? Do you get any certificate warning? Your screenshot doesn't include the address bar or any http(s)/security warnings. The browser rejects and aborts the TLS connection, but so far we don't know why.
