Port exclusions can be reserved by Docker or Hyper-V that conflict with the port used by IIS Express for a given project. You can verify this your issue with the following command to list the excluded port ranges.
netsh interface ipv4 show excludedportrange protocol=tcp
Protocol tcp Port Exclusion Ranges
Start Port End Port
---------- --------
49787 49886
50000 50059 *
50160 50259
50260 50359
51212 51212 *
56464 56563
56580 56679
57010 57109
64808 64909
In this case the range 64808 - 64909 is the cause and IIS Express will not be able to use it.
The following procedure will reserve the port used by the project.
netsh int ipv4 add excludedportrange protocol=tcp startport=64831 numberofports=1 store=persistent
Run the following to verify the port has been reserved:
netsh interface ipv4 show excludedportrange protocol=tcp
Protocol tcp Port Exclusion Ranges
