After a certificate is installed into Apache 2, connecting via Firefox browser gives the error:
[Site URL] has sent an incorrect or unexpected message. Error Code: -12263
This can occur if the firewall is blocking the SSL connection as port 443 is not open
To check and resolve this issue use the steps below:
- Connect to the website using the internal IP address, on the server network. This can be done via a browser or openssl:
openssl s_client -connect [site address]:[port] -state -[protocol]
openssl s_clinet -connect www.bbtest.net:443 -state -tls1_2
This should show the certificate that is currently referenced.
- Check if the IP address is set up correctly on the firewall
- Check if port 443 is set up correctly on the firewall. For checking IP and port numbers on the firewall, please consult your firewall vendor.
