Hi
At some point SSAS named instance service changes port after service restart. Port value in config is 0 - so it should use default port 2382 https://docs.microsoft.com/en-us/analysis-services/instances/configure-the-windows-firewall-to-allow-analysis-services-access?view=asallproducts-allversions . But why it changes ?

here is the reason - Open TCP port 2382 when installing a named instance. Named instances use dynamic port assignments. As the discovery service for Analysis Services, SQL Server Browser service listens on TCP port 2382 and redirects the connection request to the port currently used by Analysis Services.

Named instances almost always use dynamic ports. The browser is designed to handle this.
