What Can I do? I acnt understand the problem for network error on localhost:800.

I suppose your web client is trying to access a localhost server. You would need to use the hollaex prod command and apply the build to both server and the client. The web client in this case needs to know the servers API URL but instead its connecting to the localhost.
