We can’t connect to the server at rancher.server.com

Hi, I am trying to access my rancher installation with firefox and get the following

Hmm. We’re having trouble finding that site.
We can’t connect to the server at rancher.sever.com.

But when I test it with curl -k https://rancher.server.com I get a long string as follows

{"type":"collection","links":{"self":"https://rancher.server.com/"},"actions":{},"pagination":{"limit":1000,"total":4},"sort":{"order":"asc","reverse":"https://rancher.server.com/?order=desc"},"resourceType":"apiRoot","data":[{"apiVersion":{"group":"meta.cattle.io","path":"/meta","version":"v1"},"baseType":"apiRoot","links":{"apiRoots":"https://rancher.server.com/meta/apiroots","root":"https://rancher.server.com/meta","schemas":"https://rancher.server.com/meta/schemas","self":"https://rancher.server.com/meta","subscribe":"https://rancher.server.com/meta/subscribe"},"type":"apiRoot"}

I dont’ see any error messages in the rancher pods.
No problems with: ```
kubectl -n cattle-system describe issuer

kubectl -n cattle-system describe certificate


How can I open rancher from the browser. This is version 2.6.3
