Hello we are seeing some Internal server error , Any suggestions please ?


logger=context userId=3 orgId=1 uname=***** t=2022-12-15T19:42:43.520644027Z level=error msg="Internal server error" error="[plugin.downstreamError] failed to query data: Get \"[http://mimir-distributed-l](http://mimir-distributed-l)```

Looks like mimir-distributed-nginx.mimir is returning an error. you’ll have to check the logs on that.

#3

But why its throwing a plugin error ?

I would expect the plugin to throw an error if it’s trying to send a request and getting an error from the host. The error type is plugin.downstreamError . Makes sense to me, it’s like nginx giving bad gateway error.

Okay . I will look for errors on other end …
