Content Server Stopped Working

[Amalthia]

Hi,

For the last few months I've noticed that my content server in Calibre stopped working. I checked my settings and I don't recall changing anything major. I have been keeping my Calibre up-to-date with the new versions.

I did check my error logs and this is what was posted.

I'm not sure what this means and how to fix the problem?

I'd appreciate any and all help.

Thanks.

There are no recent errors in that log, elaborate on "stopped working". What happens if you click the "Test server" button in Preferences->Sharing over the net

When I click on Test Server it goes to my content server page that I can access from within my home network. However, I cannot access the content server from outside my home network. The IP address hasn't changed, my ports are opened, I'm not sure why I can no longer access the content server. I've tested this on multiple computers and my phone. It just won't connect.

The content server log wont help you in that case, as the requests are never reaching the content server. If I were you I'd double check my port forwarding rules and my firewall rules.

I did double check my port forwarding and firewall settings. That's why I'm a bit confused.

They match up.

I'm getting a message that says, "502 Bad Gateway Response Error, a bad response was received from another proxy server or destination origin server."

EDIT: I think I found a solution. My settings did match up with no-ip.com and I decided to try and enter the IP address and this time I added the : and my port number and that seemed to work. I don't know why in the past it wasn't needed but it appears now I have to add the port the address is going to at the end of the url. Thank you for your help. Knowing that the problem was on my end helped narrow down what could be wrong.
