Hi,

I tried to upload an artifact (type of rootfs) with a size of 3.6 GB. The progress indicator shows 100% but after 11 minutes I get a 504 error. I tried this several times on different machines with the same result.

Any ideas?

Thanks  
Sven

I have the exact same issue. Did you find a solution ?

Hi @Damien,

Maybe some connectivity issues in the browser? Can you try using the `mender-cli` tool? [Downloads | Mender documentation](https://docs.mender.io/downloads#mender-cli)

Hello,  
thanks for your answer.

I have the same issue with mender-cli

Sometimes it works, but most of the time it fails.  
Our mender server is local and on the same network than my build server

Hi @Damien,

Can you try to gather some information from your server to track the issue down? The most interesting parts should be the `traefik` and `deployments` logs. You can use the helper script at [mender-server-support-tool/mender\_server\_support\_tool.sh at main · oldgiova/mender-server-support-tool · GitHub](https://github.com/oldgiova/mender-server-support-tool/blob/main/mender_server_support_tool.sh) for that.
