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.

[biancat821]

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.

I am running into the same issue. Any pointers?

My problem got resolved by adding a new firewall rule to allow 50505 tcp in windows defender on my local windows11 machine :)!

[biancat821]

I managed to solve definitely this issue by changing the port.
So I have changed:

• In the file app/start.ps1
  $port = 8080
• In the file app/frontend/vite.config.ts
  All the occurrences of 50505 replaced by 8080

Maybe you can also check if you habe any other occurrence of the port number 50505 by searching in the entire project the number 50505 and replace it with 8080, if any.
Let us know if this works for you.

R served port ranges? Run the following
netsh int ip show excludedportrange protocol=tcp:
