ERROR while attempting to bind on address when launching ayon

[Liametc]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior:

When launching ayon, there is an issue that arises from the webserver not being able to bind on an address. I have narrowed it down to client/ayon_core/tools/tray/webserver/server.py where it is resorting to "localhost" as a hostname. This suggestion to fix the error works as I have tried it on my local addons install. I replaced all "localhost" instances in the aforementioned file with "0.0.0.0".

Expected Behavior:

That error should go way

Version

1.0.10

What platform you are running on?

Linux / Centos

Steps To Reproduce:

Going based off of this answer here I'm not sure 0.0.0.0 would be doing what you wanted it to. But I really know too little of networking to begin with so 🤷

@iLLiCiTiT @martastain thoughts?

[iLLiCiTiT]

Hmm, 0.0.0.0 is potential danger as it makes the server open for all adapters, instead of just the host. The localhost is alias for 127.0.0.1 (fake localhost network).

this works @iLLiCiTiT I've added that change to my PR
