Run locally: WinError 10013: access a socket in a way forbidden by its access permissions

[biancat821]

Sometimes when I run locally I receive the following error (see also details below).
PermissionError: [WinError 10013] An attempt was made to access a socket in a way forbidden by its access permissions.

The strange thing is that the application run without any problem unit yesterday and now it does not start locally.
I tried to restart several times the laptop but the issue is still there.

I had this behaviour before but at some point the issue dissappeared (I do not know how).
I worked more than one month with no problems and now the issue is here again.
But I do not understand the cause.
Any suggestion?

Hm, I see a similar issue logged here on the hypercorn issue tracker:
pgjones/hypercorn#231
Can you try changing the port, or see if the other workarounds work for you?

Dear Pamela,
Thank you very much for your kind feedback.
After many attempts, I was able to solve the issue by deleting the O.S. process named “ai.exe”.
I was trying to understand why this process sometimes is activated by itself but I honestly did not understand it yet.
However as soon as I’ve deleted that process, the local deployment worked immediately.
I am quite sure that this was the cause.

Unfortunately after that I reboot the PC and I deleted again "ai.exe", the problem came back again.
I will try to check the link you indicated.
