java.net.ConnectException: Connection timed out (Connection timed out)

@ishkabirk Try a newer release. I'm not seeing any downloads in the logs you have provided, so try to only include the relevant parts of the log. But there's a connection timeout at the end, so try to figure out where the timeout is coming from and fix that problem.

i was going through other problems as well, does the empty excel issue is being reported in v41??

@ishkabirk There are 11,000 issues (opened and closed). Go ahead and look through them:
https://github.com/metabase/metabase/issues?q=is%3Aissue

Or easier, just upgrade to a newer release.

the csv and excel i download is empty , runnning on v41.5 and the datasource which i'm trying to download is in mongodb

Hi @ishkabirk
Upgrade to a newer release: https://github.com/metabase/metabase/releases/latest

can't this be solved without the upgrade??, there are many databases connected to it and with the upgrade, what is the possibility that there might be issues with other kinds of db such as postgres, mysql etc etc

@ishkabirk We've been over this multiple times. You have not provided enough logging details to understand the problem, so upgrade to a later release first. And make sure that you don't have a reverse-proxy causing problems.

I've provided the logging details as per my understanding

What exactly you need please tell

@ishkabirk Like I wrote here:

I'm on v41.5, the table which i have created is too big to download , even the upper limit of metabase does not suffice it which is 204800 kB and the download is empty which log message as too big of data at row 1. Will this problem be solved if i upgrade to higher versions or i need to reduce the number of columns in it?
