If you want to simplify things, do this:

1. Remove all the proxy mess in between the service and network
2. Make sure it works properly, and you can address it by name
3. Add proxy back and point to DNS to it
4. Test again

Then just keep adding things back and find where it’s breaking. I’m positive you have a hostname mismatch, or a messed up DNS record if you’re using multiple proxies. Curl output would be helpful. Also check dig (hostname) to see what your DNS is responding with.

If it’s 192.168.1.1, then your DNS has the wrong address somewhere. It’s looking for 35.242

You have a loopback. Says it right there.

From your diagram it looks like you’re have two reverse proxies chained together…why?
