404 not found, rancher; how to debug and fix?

I’ve read almost all 404 not found QNAs and still can’t figure out why is this happening. This gets fixed sometimes when I do ./k3s-killall.sh and restart k3s. But will come again. I am tired of this.

And what do you expect at this location? It is not a typical rancher port, os what did you set up?

I expect rancher here. It’s a natted port.

Hi, Could you please share your nginx controller pod log?
