Hi everyone, I was wondering what configuration is required to not see the below error.



So, by default the `PREFECT_SERVER__GRAPHQL_URL` is set to <http://localhost:4200/graphql> but I want to change it some other URL. How can I achieve this?

hi <@U016LQ7AJKT> - you'll need to modify your configuration file at `~/.prefect/config,toml` (on whichever machine you're hosting Prefect Server) to look like this:
```[server]  
  [server.ui]
  graphql_url = "<http://YOUR_MACHINES_PUBLIC_IP:4200/graphql>"```

Thanks <@UN6FTLFAS>. What happens if all the services are running in containers on a server which is not accessible via public IP? Can we not point it to `apollo` server's container?

Something like, (containers are in the same network)

```[server]  
  [server.ui]
  graphql_url = "<http://apollo-container:4200/graphql>"```

Unfortunately that won't work because your _local browser_ is what's trying to access that API; if the API isn't available in the network your browser has access to, your UI will never be able to connect.

Oh! Is there any solution to this kind of problem? Also, would this affect the flow runs or just that the UI wont be working?

This'll just impact the UI, flow runs should operate as expected. There aren't any straightforward solutions but I know a few people have successfully used proxy/custom auth layers to make it work. Unfortunately that's not something we support so I won't be able to help much there

Sure, Nicholas. Thanks. I am thinking of some form of tunnelling as well. However, would it be asking too much to ask for people who have accomplished what you said above?

Hey Nick, I got the UI working, thanks. Now, when I register a flow, I the request is still forwarded to localhost. What might I be doing wrong?

Hey Nick, I got it. A very funny mistake, had to set the prefect server backend in the container that i was registering the flow from. Thanks for your help anyways.
