Afternoon
We have had VCAC 6.0.1 running for a while now without problems. From some yet unknown reason our tenants are unable to request new Catalog items, receiving error "
"Unable to complete the requested operation: An error occurred while sending the request."
We are also the error :"VCAC 6.x Error has been caught, see event logs located on the vCAC server for detail or contact your system administrator for more information." when navigating to certain tabs in the infrastructure tabs.All other VCAC services are running.
When looking in the Web_admin_error logs we see the following error:
INNER EXCEPTION: System.AggregateException: One or more errors occurred. ---> System.Net.Http.HttpRequestException: An error occurred while sending the request. ---> System.Net.WebException: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel. ---> System.Security.Authentication.AuthenticationException: The remote certificate is invalid according to the validation procedure.
None of our SSL certificates have changed or has expired.
