I have followed the guide “Replacing Amavisd with Rspamd in ISPConfig 3.1 ...” however I'm getting a 404 error when trying to access the Rspamd GUI (on Ubuntu 18.04, with the Apache 2.4 option) Any ideas how to troubleshoot this would be much appreciated.
See what happens in Apache access.log and error.log when trying that Rspamd GUI. The log files are in /var/log/apache2/ directory.
Thanks for the tip Taleman. 1. I have checked the logs mentioned, I see no errors relating to the issue, anything else I can do? 2. I am getting this in the Control Panels system log output: " systemd-resolved[7185]: Server returned error NXDOMAIN, mitigating potential DNS violation DVE-2018-0001, retrying transaction with reduced feature level UDP "
I don't know what strange error messages mean. I copypaste them to Internet Search Engines to find out. So use Internet Search Engines with Code: systemd-resolved[7185]: Server returned error NXDOMAIN
