Application deployed to User Collection not displayed in Software Center

Hi,

I have a problem at a customer where all apps deployed to a user collection are not displayed in software center.

After digging, I have found the following errors in SCClient_<Domain>@user.log

The exact translation is ;

GetCategoryValuesAsync: There was no endpoint listening at https://xxx/CMUserService_WindowsAuth/applicationviewservice.asmx that could accept the message. This is often caused by an incorrect address or SOAP action. See InnerException, if present, for more details.. Unable to fetch user categories, no endpoint found. (Microsoft.SoftwareCenter.Client.ViewModels.SoftwareListViewModel+<LoadAppCatalogApplicationsAsync>d__164 at MoveNext)

It's followed by the same error message with d__125 as you can see in the screenshots.

This server is a single server hosting MP / DP / SQL etc.. installed by myself (Current Branch 2107).

It's fully https and I never installed and removed Application Catalog role.

In the beginning of this year, app deployment to users was fully functional.

We have Co-Management installed.

Can anyone help me please?

Thanks
