Subject: PostgreSQL TCP proxy times out from Yandex Cloud Functions
Hello. My Telegram bot cannot connect to Railway PostgreSQL
from Yandex Cloud Functions.
Public endpoint: switchyard.proxy.rlwy.net:27269
Resolved IPv4: 66.33.22.232
Inside Cloud Functions:
- DNS resolution succeeds.
- Opening a TCP connection times out.
- asyncpg also times out during connection establishment.
From my Windows computer:
- Test-NetConnection to the same endpoint succeeds.
- Connecting with asyncpg and loading database records succeeds.
Yandex Cloud support says outbound TCP connections to this port
are not blocked by their platform.
Could you check whether the TCP proxy or network filtering
affects connections from Yandex Cloud, and advise what additional
network diagnostics you need?

It seems like Yandex Cloud is dropping traffic. Unfortunately, Railway isn’t able to do anything about this, and you’ll need to reach out to Yandex Cloud to resolve this issue.
