Does “virtualmin check-connectivity” work reliably?

Never used this command before but was wondering if this is valid output because of the fact that the site can be reached and sports a valid SSL certificate:

$ virtualmin check-connectivity –domain EXAMPLE.COM
    Status: 4 errors
    Error1: web : Website request failed : 500 Can't connect to EXAMPLE.COM:80 (SSL connect attempt failed error:0A0000C6:SSL routines::packet length too long error:0A000139:SSL routines::record layer failure)

@Steini,

I’ve never actually used this feature before, but assuming it’s doing an ICMP request for the “ping” process, you’ll need to make sure you’re allowing inbound/outbound ICMP requests through your firewall, otherwise a “ping” will fail.

For other requests, assuming it’s using the “telnet” approach to connect to ports checking availability, make sure each of the ports you are testing “25 - smtp”, “80 - http”, “443 - https”, etc can get through the firewall as well (typically this is setup by default if these services are being used and otherwise work).

Apologies, should’ve mentioned that I disabled the firewall for testing purposes. Same result.
