--listen acting strange

[TWIISTED-STUDIOS]

I recently installed the extension for HTTPS for self-signed cert, I usually run the app with --listen as I like the availability to run on any device on my network.

Before when running this way I was still able to access the interface using either localhost or the IP of the machine on the machine it was running, I'm now no longer able to access the interface on the machine that's hosting the application, either through localhost,127.0.0.1 or even the internal IP of the machine, but I am still able to access the interface from an external device using the IP address of the hosting machine.

Has anyone come across this problem or know the reason as to maybe why this isn't working anymore?

Update Tested removing --listen from the arguments and still can not access the interface on localhost. Removing the Extention causes the localhost to work again while using --listen.

Thank you to anyone and all people able to help me with this issue!
