Repository 'SUSE-CAASP-3.0-Pool' is invalid

Hello together.
I have Kubernetes Cluster on Caas 3.0
I had to update internal TLS/SSL Certificates, to do it, i took the documentation (https://documentation.suse.com/suse-caasp/3/) and does the steps from Administration Guide (9.9 Replacing TLS/SSL Certificates - Page 125)

On Step 7:
docker exec -it $(docker ps -q -f name="salt-master") bash -c "salt-run state.orchestrate orch.kubernetes" 2&>1 > salt-run.log

I get following error from our 3 master-nodes-minions:

The Repository seems to be disabled… Why?

I heard about the Caasp 4, but we don’t have the resources to migrate full cloud on new Cluster at this moment.
Can somebody help me to solve it?
Because of this issue my dex-pods are down…

Hi, can you confirm that your nodes are fully registered? Type command SUSEConnect -s
Note that CaaSP v3 is now out of support. You may need to migrate to CaaSP v4.

Hi Brice,
thx for your message.
yes, all of 3 Master-Nodes are Registered:
[{“identifier”:“CAASP”,“version”:“3.0”,“arch”:“x86_64”,“status”:“Registered”,“regcode”:“REGCODE*”,“starts_at”:“2020-05-01 00:00:00 UTC”,“expires_at”:“2021-04-30 00:00:00 UTC”,“subscription_status”:“ACTIVE”,“type”:“full”}]
4 Worker nodes also.

and yes, i also know, that V3 is out of support, it was installed in 05.2019 from SUSE Installation Partner with words “don’t worry”, you can upgrade later… Now i can’t manage this upgrade because of missing time resources. It will happen, some when in end of 2020.
Anyway… it seems in my eyes that the SUSE Repository of V3 is offline…

Can someone confirm, that access to the v3 Package-repository is given?
