09/17/2020, 5:09 PMHi, I am having a problem installing prefect server on Ubuntu 20.04. The UI can't connect to the backend. I tried the hello using curl and got a response. But the default connect to http://localhost:4200/graphql isn't working. Can someone help?

Hi Nils!
Can you send along the error you’re seeing? Also, on the machine you’re calling
prefect server startprefect backend serverDylan

That generates a config to point prefect at your Prefect Server instance instead of Prefect Cloud

And when you visit localhost:8080 you’re not seeing a UI connected to server?

Looks like your server instance spun up correctly

Can you connect to the API using a graphql client on your machine?
Dylan

If not, does your machine have any network rules in effect which would keep the UI from accessing your localhost?

It looks like the UI isn’t being served on the same machine?

Try updating localhost in your Prefect Server graphql endpoint to
<http://172.16.1.98:4200/graphql>n
