Azure Relay Does not work on East US location

Question

Recently we have seen that our Relays stop working on EastUS location. We are getting timeouts wheny try to connect to relay. On East US 2 it works fine.

The issue is reproducible only with HTTP protocol. Websockets implementation works fine.

How to reproduce:
Create new Relay in East US location
Run Server and Client from examples
https://github.com/Azure/azure-relay/tree/master/samples/hybrid-connections/dotnet/simple-http

Server output:

dotnet run (your relay settings) Online Server listening =====HEADERS===== Host: YOUR_EAST_US_RELAY.servicebus.windows.net Via: 1.1 YOUR_EAST_US_RELAY.servicebus.windows.net
=====BODY=====

Client output:

{"error":{"code":"GatewayTimeout","message":"The request was routed to the listener but the listener did not respond in the required time. TrackingId:0b5b8d2b-83de-439f-b8b4-3105bf669c46_G9, SystemTracker:YOUR_EAST_US_RELAY.servicebus.windows.net:test2, Timestamp:2025-02-04T15:57:58"}}
