Assessment failed: Unable to connect to the server

You are doing something wrong.

Nginx? Apache?

nginx -T

or

apachectl -S

Or you have additional firewalls. Linux over Windows? Then you have to check the Linux- and the Windows-Firewall.

apache version 2.4.38
apachectl -S results in the following:
AH00526: Syntax error on line 33 of /etc/apache2/sites-enabled/000-default-le-ssl.conf:
SSLCertificateFile: file ‘/etc/letsencrypt/live/gordonsweb.uk/fullchain.pem’ does not exist or is empty
Action ‘-S’ failed.
The Apache error log may have more information.

Server also connect direct to the router by Ethernet cable.

Use sudo or root …

sudo apachectl -S

There is no port 80 vHost with gordonsweb.uk.

And (good) there is *:80 defined, not a single ip address.

So

curl https://gordonsweb.uk/

should work from that machine. If yes, it’s a router- or firewall problem.

curl https://gordonsweb.uk/

curl: (6) Could not resolve host: gordonsweb.uk

Hi asghar,
Server not down. Just not accessible from internet.
problem with configuration
Cheers

JuergenAuer,
Ran: curl https://gordonsweb.uk/
Result: curl: (6) Could not resolve host: gordonsweb.uk

Please could you explain your comment:
" There is no port 80 vHost with gordonsweb.uk ."
“And (good) there is *:80 defined, not a single ip address.”

could you please help me correct the above if that is what the trouble is.
Kind Regards

JuergenAuer,
Ok I have a second web server I’ve just done.
It’s only HTTP but works on external WAN
http://www.gordonsweb.uk

Both domains (non-www and www) have the same ip address - https://check-your-website.server-daten.de/?q=gordonsweb.uk

Host T IP-Address is auth. ∑ Queries ∑ Timeout
gordonsweb.uk A 82.7.10.112 Brighton/England/United Kingdom (GB) - Virgin Media Limited Hostname: cpc146294-brig23-2-0-cust623.3-3.cable.virginm.net yes 1 0
AAAA yes
www.gordonsweb.uk A 82.7.10.112 Brighton/England/United Kingdom (GB) - Virgin Media Limited Hostname: cpc146294-brig23-2-0-cust623.3-3.cable.virginm.net yes 1 0
AAAA yes

Both port 80 answer, both port 443 have a timeout.

Looks like your network configuration is buggy if there are different servers.
