Issue Summary

We host Redash ourselves via AWS. Some of our users can access to the dashboards, but some of them cannot, it seems like there is always a random portion of all our users encountered with ERR_CONNECTION_TIMED_OUT with website took too long to respond. Any idea where we can look?

Technical details:

  • Redash Version: 8.0.0+b32245
  • Browser/OS: Chrome
  • How did you install Redash: AWS hosted

Welcome to the forum :wave:

How many concurrent users do you have? It’s possible the webserver is overloaded.

Hi Jesse,
Thank you for replying! We have in total 37 users who have access to Redash. I do not think many users are using at the same time, maybe less than 10. Is there a way to improve the situation if the problem is overloading webserver? Thank you!

I agree. The default Redash configuration can handle 100x that many users without problems.

A few other things you can check:

  • what do your docker logs say? do you see failures on the server process?
  • how many web workers are configured in your docker-compose.yml?
  • For users who successfully log-in, does everything work normally? Or do they see many errors?
  • Are you running a proxy in front of Redash somewhere?
