Hi @faresalokeeli
Please post “Diagnostic Info” from Admin > Troubleshooting.
Are you using a load-balancer or proxy in front of Metabase? Then make sure to adjust the timeout of those, so they don’t close the connection:
https://github.com/metabase/metabase/issues/12423 - upvote by clicking :+1: on the first post

we are using Jetty web service which embedded in Metabase JAR file . we don’t have load-blancer or proxy

@faresalokeeli Then I guess you have connection problems between the browser and Metabase.
You can probably see something by monitoring the network traffic on the server.

I tried to monitor the network traffic on the server, but I did not find anything.
could you give way to monitor Jetty web service or path of the error log of Jetty

@faresalokeeli You can also monitor the traffic on the client. You can enable debug/trace logging on Metabase:
