Could you attach as a zip to this thread /etc/webmin/miniserv.conf and /etc/webmin/config files and /etc/webmin/status directory (or you could send it in a private message to me directly).
Oh, sorry, I tried hitting the URL he provided, but didn’t notice the prefix (and I also got a 404, assumed it was rewrites in Authentic, but I guess it’s not, just the XHR protection kicks in).
So…yeah, this is a prefix problem. @harryf you should really mention you’re proxying to Webmin, if you’re proxying to Webmin. A whole bunch of other stuff happens in a proxied connection.
No, I’m not proxying, I don’t believe. I thought I’d just try typing in the URL in your screenshot directly to see what response I get and as you said it’s expectably a 404.
I have since tried Incognito with Disable Cache and the problem seems to be solved, which is too weird.
Never had this problem before with any webapp, and with any of the other modules on Webmin/Virtualmin.
I’m not sure what webprefix is in the Virtualmin context. I just have a basic vanilla Virtualmin install on Ubuntu.
Does disabling cache really worked or incognito mode, which also disabled all extensions loaded? Perhaps, the source of the problem was a browser extension?
There are no extensions in Incognito or in Safari. I think it was a server-side issue still, but it’s gone now and seems impossible to further investigate at this stage.
