Hi @IgorKuznetsov93,

I got the same issue with you, how did you fix it? My ioredis version is 4.27.4

Thanks a lot

Hi! I thought I had solved the problem, but no, my logger just broke. Unfortunately, the problem still remains Reopen issue

Getting the same issue on the same ioredis version. Any update?

Hi Has anyone fixed this issue yet ? @zry754331875

[olasundell]

We're also seeing this issue, quite a few years have gone by now. Any plans on fixing it? We're using version 5.3.0.

[luin]

The error is expected if all your sentinels were not available at that time. More information are helpful for us to debug it further if that's not your case.

[ChrisNoSim]

Our applications have the same problem every 40 min, when we get that kind of error. We are using the Bitnami helm chart with a 3 node setup of REDIS/sentinel. And all sentinels are online and reachable via an internal google loadbalancer service.. If you need more info please let us now. Is there some kind of tasks that run every 40 min or a connection reset or something else? Thanks in advice.

[mahesh-av-qp]

Our application is not even able to establish the connection the very first time, Setup is pretty simple I am just testing in my local system and I have only one sentinel and one redis instance (both are running on docker

I also observe random timeouts towards redis, with a mix of "All sentinels are unreachable" and generic timeout errors being printed. The sentinels appear to be completely healthy.

The application performs around 1-2k queries per second and the timing of the error event seems completely random, but there are usually around 500-1000 such errors per day:

I have currently disabled retries via maxRetriesPerRequest: null, but will check if enabling retries will get rid of the errors. Other options I tried are enabling enableAutoPipelining but it had no effect.

[victor-develop]

Problem still exists...
