This is still ongoing, but we are getting assistance from support. Below was the response after collecting CDF from the server VDA and CWa trace logs. "The issue is when the reconnect happened that the token response from ticketing is unknown." 2024/02/16 16:24:12.34286,7216,5040,1,BrokerController,,,,1,Information,"Activity stop: Citrix.Cds.Broker.TicketingService:TicketingService:Validate", span.name=TicketingService:Validate, span.kind=Internal, otel.status_code=ERROR, otel.status_description=″GetClientValidationData: Unknown launch token: [scrubbed launch token]″UnknownLaunchTokenException: GetClientValidationData: Unknown launch token: [scrubbed launch token]

We recently moved our EMR (our largest used Citrix app by far) to Citrix Cloud DaaS. Since doing so, we have been getting random (highly difficult to replicate) reports of users getting a basic "Access Denied" error when trying to launch an application. This is happening internally with no ADC in the picture, other than to LB the SF servers. We have checked licensing (as several CTX articles have noted) in Citrix Cloud and that doesn't appear to be hitting the ceiling. We finally were able to capture as requested by Citrix Support, but while they are reviewing the logs, I'm curious if anyone else has encountered this with Citrix Cloud DaaS? We are not seeing any obvious events in the event viewer logs of endpoint, CCC, SF, VDA, or LIC. If the user restarts the endpoint or CWa, they can launch just fine. Versions: Win10 endpoints running CWa 2203 CU2 Server 2019 VDA's running 1912 CU6 Storefront is 1912 CU6 running on Server 2012 R2 (migration to Server 2019 in the works) On-prem License server is 11.17.2.0 build 42000, but we have configured the VDA's to use the DaaS licensing
