I've just tried reploying everything and changing the O/S image to use Server 2019 Datacenter.

 

Same issue with with Get-RdsSessionHost -TenantName <tenant> -HostPoolName "<hostpool> returning nothing.

There was an additional error in the eventlog with the RDAgentBootLoader:

 

BootLoader exception:System.AggregateException: One or more errors occurred. ---> System.Exception: Could not resolve a service of type 'Microsoft.RDInfra.ScheduledTasks.HostedServiceExecutor' for the parameter 'hostedServiceExecutor' of method 'Configure' on type 'Microsoft.RDInfra.RDAgent.Service.Startup'. ---> System.ArgumentException: IDX12739: JWT: '[PII is hidden. For more details, see <a href="<a href="https://aka.ms/IdentityModel/PII" target="_blank">https://aka.ms/IdentityModel/PII</a>" target="_blank"><a href="https://aka.ms/IdentityModel/PII</a" target="_blank">https://aka.ms/IdentityModel/PII</a</a>>.]' has three segments but is not in proper JWS format.

 

 

Currently getting both this error

 

ErrorSource       : RDBroker
ErrorOperation    : AuthorizeUser

ErrorCodeSymbolic : ConnectionFailedUserNotAuthorized

and this error

Matt88 : Do you have any firewalls that would limit outbound connectivity? The error of "NoHealthyRdshAvailable" makes sense if Get-RdsHostPool didn't return anything.

 

It largely looks like it can reach the service or there's something on the image that is preventing the right DLLs to be loaded at registration time.

    Christian_Montoya - I don't have any problems getting out to the internet

     

    I've tried psping rdbroker.wvdselfhost.microsoft.com:443 and rdweb.wvd.microsoft.com and both work fine.
