Site not working after installation - Ubuntu 18.04/Apache


I have just installed the SSL certificate and it is not working any more.

It looks like this is likely to be a firewall problem because connections to TCP port 443 on your server simply time out (rather than being accepted or rejected outright), while port 80 works. This is typical of firewall problems where packets for a particular port are simply dropped.

The problem is most likely not directly with your certificate.


Not according to 3 different locations I just scanned from.

You doing some kind of geo-IP filtering?

Kindly help urgently,
