Do you mean Docker compose?

If yes then, did you already check the documentation regarding it i.e.

I check done I run Grafana 8.5.6. no problem
I update 9.2.2 I see error bad request

Can you please provide the steps of reproduction so that the community can also try to reproduce it on a test machine?

Also, share your docker-compose file so that I test it as well

Thanks.

Hi @prasinp,

Can you please provide the steps of reproduction so that the community can also try to reproduce it on a test machine?

Also, share your docker-compose file so that we can check it.

Lastly, 2 more additional questions from your recent comment i.e. :

1- As you said that the 400 error appears not always but only from time to time. Can you please check the logs whenever it happens as the logs are located at /var/log/grafana/grafana.log

2- You said initially that you are using docker-compose but later in the recent comment saying about pulling grafana via git. I do not completely understand it so kindly explain in a bit more detail as initially asked i.e. provided step-by-step details of reproduction.

I found error
*476119 upstream prematurely closed connection while reading response header from upstream

Thanks.

So to my best knowledge, this does not look like a Grafana issue but either:

1- Docker side (network)
2- Web server side (Apache/Nginx timeout)

For the latter one, it can be fixed by increasing the timeout value in the configuration file.

But if there is no Web server or even a reverse proxy involved then, probably ask Docker Community about it.

I hope this helps.

Hi @prasinp

Did you find a solution or is this is still on-going?

We would like to know the updated status :slight_smile:

Thanks
