EACCESS: permission denied

Hi,
yesterday i worked with radzen, all was fine. Today radzen shows the update message, so I started the update. Now I receive the following error (after reboot)

ng-cli: Error: listen EACCES: permission denied 0.0.0.0:8000
at Server.setupListenHandle [as _listen2] (net.js:1211:19)
at listenInCluster (net.js:1276:12)
at doListen (net.js:1415:7)
at processTicksAndRejections (internal/process/task_queues.js:77:11)

the firewall parameters for dotnet.exe are unchanged.

Any idea?

Kind regards,

Ralf

Hi Ralf,

Check this thread for more info:

Hi,
before my post I check the named thread, but without success.
But I found the solution:
windows subsystem for linux - How to fix listen EACCES: permission denied on any port - Super User
The error appears because the port used belong to reserved ports for Hyper-V.
This port range changes when I restart my computer, so sometimes I get the error sometimes no.
To check reserved ports by windows you can use(cmd/powershell):

netsh interface ipv4 show excludedportrange protocol=tcp

At the moment I use port 50500...
Thanks,
Ralf
