Unable to Access code-server - White Screen Issue for Guests on Local Network

I am encountering an issue while using code-server on Coder. When I access Coder from my virtual machine as the host everything works fine. But when i log in to coder on my local machine as a guest the code-server application opens and only shows me a blank white screen. I am running my own Template, so i guess my problem is somewhere in my main.tf file.

Thank you for your Assistance.
