Since the most recent deploy at 2026-04-29 15:06:48 UTC, our FastAPI service has been unable to make any successful outbound HTTPS call.
Every attempted outbound connection from the container fails with httpx.ConnectError: [Errno 101] Network is unreachable.
I have another environment in the same region with exactly the same version and config which is able to make outbound calls.
I effectively have a downtime in my production server, so this is urgent.
Please help.

Enable Outbound IPv6 in your service settings and see if that helps.

Not sure if this was the issue, but once I redeployed it was resolved (with the ipv6EgressEnabled)
