Secure Connection Failed An error occurred during a connection to xxx Peer using unsupported version of security protocol. Error code: SSL_ERROR_UNSUPPORTED_VERSION
Browser FIrefox
I was having that same issue in Firefox, after checking the answer of Brando Zhang, I try only changing the “security.tls.version.enable-deprecated” to true (in about:config) and it worked!
That way, you don’t have to lower the TLS security version
