Rancher ingress return 404 to service.
Setup: I have 6 VMs, one Rancher server x.x.x.51 (where dns domain.company is pointing to, TLS), and 5 VMs (one master and 4 worker x.x.x.52-56).
My service, gvm-gsad running in gvm namespace:

When i access it with https://domain.company/gvm then i get 404.
However, when i change the service to NodePort, i could access it with x.x.x.52:PORT normally. Meaning the deployment is running fine, just some configuration issue in ingress.
I checked this one: https://stackoverflow.com/questions/52442868/rancher-2-x-thru-ingress-controller-returns-404 but it does not help.
Thank you in advance!
Figured out the solution.
The domain.company is pointing to rancher (x.x.x.51). Where the ingress is running on (x.x.x.53,.54,.55,.56).
So, the solution is to create a new DNS called gvm.domain.company pointing to any ingress (x.x.x.53,.54,.55,.56) (you can have LoadBalancer here or use round robin DNS).
Then, the ingress definition is gvm.domain.company and path is "/".
Hope it helps others!
