Misc: Error trying to bind the API to port 5115

[Buttercream91]

That error message pops up after installing Hass.agent followed by "Make sure no other instance of HASS.Agent is running and the port is available and registered.

I don't know how to ensure the port is available and registered. I successfully installed Hass.Agent on another pc on the network, is that what it means by no other instances? Please send help.

I have made sure there is no other process blocking the port. But I get the same error. the logs says following:

System.Net.HttpListenerException (5): Zugriff verweigert

if i start hass-agent as admin it starts two instances. local-api works now but mqtt doesn't (it alternates really fast between on and off)

[LAB02-Admin]

Can you please close all instances of hass.agent, then open an elevated command prompt, and run these commands:

netsh http delete urlacl http://+:5115/
netsh http add urlacl url=http://+:5115/ user=Everyone

Afterwards, restart hass.agent (as a normal user, no elevation required) and see if it's fixed

ok user=Everyone didn't work: The SDDL could not be created. Error: 1789 but with my user (there is only one) it worked. thanks

Edit: if windows is German it need to be user=Jeder
