Experiencing instable redis

The redis addon, created with fly redis create is very very instable in our environment. After a short time we get connection issues:

read error on connection to fly-xxx-xxx.upstash.io:6379

Any ideas?

While I found no way to get access to redis logs, it’s hard to debug right now… The instance in network seems to be available, because deleting the instance throws an other error like cannot resolve host.


Do you have any idle connections to Redis? Those might get closed due to a 60s default idle timeout. Or are you seeing read errors for actual reads?

We’re you ever able to resolve this?

I am seeing the same issue on a Laravel install where it was working just fine yesterday. I am able to ping the host from the VM (once I installed iputils-ping).
