Yes, absolutely. If AnyRouter cannot resolve the hostname of the upstream server to an IP address, it won't be able to connect. This will often manifest as a 520 error, and because the connection never fully establishes, the response body will be empty. Verify that DNS resolution is working correctly from the AnyRouter server.
