Issue Help "Failed to connect to statics.tls.security.mozilla.org port 443"

[sebastianapeng]

Hi,

Anyone having this issue lately? I can't install SSL certificate for my domains.
Error: Could not get Mozilla tls config: cURL error 28: Failed to connect to statics.tls.security.mozilla.org port 443: Connection timed out (see libcurl - Error Codes)

Thanks!

Looks like the connection is firewalled. Check that you can connect from this server with:

$ telnet statics.tls.security.mozilla.org 443
Trying 18.66.15.116...
Connected to statics.tls.security.mozilla.org.
Escape character is '^]'.

Hi Igor,

Thank you for reaching out.

Looks like the connection is firewalled. Check that you can connect from this server with:

$ telnet statics.tls.security.mozilla.org 443
Trying 18.66.15.116...
Connected to statics.tls.security.mozilla.org.

After testing above.

# telnet statics.tls.security.mozilla.org 443
Trying 65.8.66.2...
Trying 65.8.66.86...
Trying 65.8.66.83...

Check firewall rules for your or your service provider.
