FAM - Error after upgrade to 8.2

Has anyone run into an issue with the ACM service after upgrading to 8.2?

Below is the error message received from the log:

Error,Microsoft.AspNetCore.Server.Kestrel.Core.Internal.HttpConnection.SelectProtocol - HTTP/2 over TLS was not negotiated on an HTTP/2-only endpoint.

Hi @barbara_hodgkin 

Thanks for very helpfull query.
I monitored proces FAMCertificateManager.exe with Procmon64

The steps are
1. creates certificate and key
2. Uploads to database (certificate changes in db)
3. deletes this certificate  from local machine certStore( very strange behavior )
4. service uses old certificate what causes HTTP/2 errors

Screen from write operations attached
