Dear community,
I am recently trying to install WeBWorK 2.17 Ubuntu Server 22.04 LTS Amazon Machine Image. Right after the launching, I was able to access the homepage of WebWork with http://(Public IPv4 address)/webwork2. However, after updating the webwork2 and pg code and restarting apache2, the above URL stopped working and kept showing the URL is not found on the server. Does anybody run into this situation and how do you resolve it?
Thanks,
Ben
