That is how the signal protocol works, it’s end to end encrypted with the keys only known between the two ends.

The issue is that servers are needed to relay the connections (they only hold public keys) because your phone doesn’t have a static public IP that can reliably be communicated to. The servers are needed to communicate with people as they switch networks constantly throughout the day. And they can block traffic to the relay servers.
