Gitlab with Caddy

Hello. I am trying to run gitlab alongisde with Caddy. I have followed

But each time I try to access my hostname I get the following error message

I am not sure how to fix this error, I tried tinkering the with external_url and reconfiguring but nothing seems to work. This is my CaddyFile {
	proxy / http://localhost:4949

On my production log file I dont see any error except for maybe

Raven 2.5.3 configured not to capture errors: DSN not set

However I cant seem to access as it returns connection refused
