Hi,

I have node-red running in docker.  
I see that this question is asked a lot. I get an error when I go to the dashboard.

If I check the log I don't see much usefull info :

The last line was me restarting the Zigbee2Mqtt image.

How can I troubleshoot this?

Welcome to the forum.

Are you running the browser in the same machine that is running node-red?

Are you using the IP address of the node-red docker container?

Do you have a good reason for using docker? If not then don't.

I have found the problem. It was my Ngnix Proxy Manager. I had to enable websockets and then it worked.
