Hi,

I am new to metasfresh and was able to start the docker instance. However it shows a blank page. I followed a potential solution described here ([White page solution / Weiße Seite Lösung (reverse proxy nginx caddy) · Issue #61 · metasfresh/metasfresh-docker · GitHub](https://github.com/metasfresh/metasfresh-docker/issues/61)) pertaining to CORS error however problem still persists - unable to fetch resources. Any ideas?

Hi @kljvwejf

This looks like the `webapi` service is either not open or is running into an error.  
You can check if the port is open using eg.:  
`telnet localhost 8080`

You can check the servers logs by navigating to where your `docker-compose.yml` is located and then use this command: `docker-compose logs -f`

Looks like I might have the same problem.  
Did you find a solution?
