SMT issue with SLES 15 SP5

Hello we have some issues with smt, we are missing the 15SP5 repo. It shows that it cannot be mirrored. What do I have to do in order to make it mirror? 15SP4 is working

The server is a SLES 12 SP5

Also smt-sync is giving this weird errors:

Downloading Product and Repository information
Unexpected Content Type
Error while fetching Product and Repository data.
Downloading Subscription information
Download (100%)
Update DB (100%)
Downloading Order information
Downloading Orders skipped
Flagging repositories which can be mirrored
Unexpected Content Type

Thank you!
