Catalog Charts refresh fails

Hello Rancher-Community.

I am using Rancher 2.3.2 and since a few weeks I can not use Catalog Apps.

I’ve already posted an issue on catalogs are not reachable "http: server gave HTTP response to HTTPS client" · Issue #24094 · rancher/rancher · GitHub but without respons.

I am not sure whats the problem here.

Hope someon can help me.
Thanks.

never mind: Istio was enabled on cattle-system, it caused several traffic issues on my cluster.
