Sudden error message today not seen before: 502 Bad Gateway
Web Server: Cherokee (latest)
WebDAV Server: WSGIDAV
WSGIDAV is running as a separate server from Cherokee. Suddenly today on my locally installed webdav client, I am getting 502 Bad Gateway errors when my client tries to delete/move/rename. I have restarted my Linode several times, restarted my laptop, restarted my local client, upgraded my local client, upgraded Ubuntu and still get the error.
I thought maybe something on my disk image was corrupted so I edited my Linode boot profile to point at a disk image I made as a copy to my main one a couple months ago. It also was returning the 502 error. I can map Windows to my webdav and there are no issues. It only seems to be through the webdav client that this error is showing up. It was not there yesterday and I have never seen it before. Tech support suggested I post here.
UPDATE: I took my laptop home and what I was doing worked fine on my home network. I suspect that something about my office proxy changed in the last 24 hours resulting in the 502. So it appears that the error was not being generated by my Linode server, but as it came through the proxy. If the problem reappears tomorrow at work, then that is the cause.
