We have recently updated our Jitsi server to 2.0.5076-1 running on Debian 10. The app works fine in a browser, but we are no longer able to check the site certificate and TLS config using openssl/nmap/wget or https://www.ssllabs.com/ssltest/
Browser reports: TLVv1.2 connection using TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
SSLLabs reports: Assessment failed: No secure protocols supported
wget reports: GnuTLS: The TLS connection was non-properly terminated. Unable to establish SSL connection.
nmap reports: No response from server: EOF
I am sure there is something wrong with the nginx configuration, but I cannot work out what it is.
We are using a lets encrypt certificate and have used the /usr/share/jitsi-meet/scripts/install-letsencrypt-cert.sh to configure nginx.
I would be grateful if anyone could help me shed some light on this.
