UI connection refused

Rancher 2.x

Hi,

I has setup a cluster in Rancher v2.4.5 for running 2 months, but several days ago, I try to login the Rancher UI, Chrome return “ERR_CONNECTION_REFUSED”.

I got these log from the Rancher container:

The servers and workers are working fine, but only I can’t get into UI for management.

Any help please

Thank you!

Did you ever get this fixed? I had a similar issue the other day with my Rancher installation?

No, I had reinstall the whole cluster after some try.
The rebuild process is faster than fixing the problem for me.
