I am having trouble with my Jail-server for a client. They recently upgraded their moodle to 3.5 and the jail server has failed to work again. The plugin works correctly. I get to this page. I am using ubuntu 17.10.
It used to work before the upgrade. I spent two days on this issue. I recreated the certificate. When I click on the link it doesn't ask me to accept a certificate.
Also I dont get an OK page when I go to the server[port]/ok. It just displays the page took too long to respond
