Gateway - Condor logs an wallet error when Gateway is unavailable on another server

Condor logs

What happened

This was noticed while using Condor with multiple Hummingbot API servers. Gateway was available on one server but was not running on another. When Condor requested the other server’s Gateway wallets, Hummingbot API correctly returned 503 Gateway service is not available, but Condor logged the expected condition as an error with a full traceback.

    )
aiohttp.client_exceptions.ClientResponseError: 503, message='Gateway service is not available', url='http://hehe-its-a-secret:8000/accounts/gateway/wallets'

The WebUI already treats this situation as “no wallets” or a muted Gateway-unavailable state. A server without
Gateway should be shown as unavailable without producing an error-level traceback during normal multi-server use.

Steps to reproduce

1. Configure two accessible Hummingbot API servers in Condor.
2. Start Gateway on server A and leave Gateway unavailable on server B.
3. Select server B then check the condor logs.
4. Or change the API server at the top then observe condor logs
5. Observe an error and traceback for GET /accounts/gateway/wallets returning 503 Gateway service is not available.
