Citrix DaaS service is migrating the communication channel used to access some Hypervisors. This migration will result in a more stable and higher performing connection. This transition will be performed on a rolling basis starting in Q1 2025.
Ensure your cloud connections can access the Citrix Point-of-Presence URLs - *.nssvc.net (including all subdomains) as per the DaaS requirements here: https://docs.citrix.com/en-us/citrix-cloud/overview/requirements/internet-connectivity-requirements.html#citrix-daas-service-connectivity
In cases where your organization is unable to allow wildcard FQDNs due to security policies, a list of all the FQDNs used by Citrix DaaS is provided in allowlist.json. Failing to allow uninterrupted access to these FQDNs from Citrix Cloud Connectors could result in service disruption when the transition takes place.
