Hi @RezaNamin123,
Welcome to Skyline Communities !!!.
Post converting PSC to embedded, we need to reconfigure the endpoint. We need to change 'Use Custom SSO Configuration' to no unless custom SSO domain is used. Once done, the vCenter endpoint will start communicating with the skyline collector and the functionality will be restored.
Sincerely
