Tried

PREFECT_API_URL

but doesn’t seem to work (seems obvious in retrospect)

Hi @Ziyao Wei - setting

PREFECT__CLOUD__API

should work!

Yep - I’m trying to run the server + UI on a server, but the UI is trying to query localhost:4200

check out the discussion on this github issue for how to update where the UI points to: https://github.com/PrefectHQ/prefect/issues/2237#issuecomment-609917317

so sed is still the method for now?

Sed will work but the true way is to rebuild the site with the value that you want; the docker image that server uses by default is a pre-built site which means the value is hard coded unless you rebuild

Cool - so if we rebuild we can specify the server URL in an env var?

Note quite - you need to update the .env file / references that Scott references in that issue; most JavaScript applications don’t respond to your local environment unfortunately

Thanks for the help - that worked!
