Describe the bug

• I installed NPM from docker hub latest. I add a proxy host to forward traffic to a host on my network on port 8080. It works ok. I managed also to add a Letencrypt SSL certificate without any issue. I can reach my site with the domain name.
• If I try to add a custom location for instance for /myapp and point it to another IP on same network as previous and port 9090 it takes proxy host offline after saving

Nginx Proxy Manager Version
v2.11.1

This appears to have happened in the past. https://github.com/NginxProxyManager/nginx-proxy-manager/issues/929

Reproduce the failure with the jc21/nginx-proxy-manager:latest Docker image by adding a proxy host, then saving a custom location such as /myapp targeting another IP and port. Compare the working proxy host with the offline state and review the related issue #929; done means saving the custom location no longer takes the proxy host offline.
