Issue Summary

A query cannot be saved with very small and seemingly innocuous changes, for example:

  1. This query can be saved

  2. Adding a space between “ROUND” and “CAST” on line 6 and the query can no longer be saved

Your docker-compose file looks good :+1:

A few questions for you:

  1. Please open your browser’s network inspector. When you click the save button, what does the network response look like when the save operation fails?
  2. On your droplet, run the following and then click the save button in your browser: cd /opt/redash && sudo docker-compose logs -f --tail 100. You should see a more precise error about what went wrong.
  3. What kind of data source does this query use?

Oh thanks for your pointer! Upon checking the browser’s network inspector, I think the error is because I set the DO instance hosting redash as a subdomain of another website protected by Cloudflare. The error from the network inspector is from cloudflare blocking the POST request sent to that subdomain

Do you have any tips for this scenario besides moving the Digital Ocean instance outside of Cloudflare firewall?

I think I figured it out. I can specify firewall rules specific to each subdomain. Thanks! You can close this topic.
