We have installed moodle-3.9 and Jail-server-2.5.3 for Moodle-VPL in Ubuntu-18.04 desktop machine (one machine for Moodle and another machine for jail server). To verify the working conditions of Jail-server, I used the following commands on URL.
First URL reports "OK" on the web browser and the second command (i.e https://192.168.49.65:443/OK) shows warning report. Here I have attached the error report for your reference.
We can execute moodle & jail server inside the college without any issues. But when we trying to execute from outside of our college, it will not execute the coding and also it does not report any error. We thought may be the above warning the browser unable to communicate with jail-server while trying from outside LAN. How to overcome this "HTTPS" issue.? how to access jail-server without the above warning? kindly help to solve these problems.
