Hi I'm using the latest prefect and helm chart. Despite setting
ui.apolloApiUrl
my UI is reporting it fails to connect
Couldn't connect to *Prefect Server* at *<http://localhost:4200/graphql>*
if i describe the deployment I see PREFECT_SERVER__APOLLO_URL is set = what I specified in
ui.apolloApiUrl
c

Hi, if it’s graphQL, it’s definitely 1.x, as 2.x uses REST api instead. What do your values look like ?

For 1.x, my apollo URL looks like this:
Copy code
- name: PREFECT_SERVER__APOLLO_URL
          value: <http://localhost:4200/graphql>
if that’s not connecting, i’d suspect maybe a configuration error elsewhere, not necessarily in the URL itself?
