Solved 15.5 Debian ISO, no console

[Mike Hammett]

I have a PBX (Debian ISO) that I can't get the management console to respond with anything. netstat -nap shows the nginx process listening on 5000 and 5001. The error happens in Chrome and IE.

This site can’t provide a secure connection
dna.il.3cx.us sent an invalid response.

• Try running Windows Network Diagnostics.

ERR_SSL_PROTOCOL_ERROR

That looks like what happens if you tried to do HTTP to the HTTPS port or vice versa. I can reach that instance just fine from here

Hello @Mike Hammett

I will with @cobaltit on this. Make sure that when trying to access the instance using the FQDN you use https and port 5001.

I swore I tried all combinations of http, https, 5000, and 5001.

Eventually, it just worked again. *shrugs*
