Hello, I am currently trying to set a prefect orion server in a docker on an EC2, however this error appears on the UI

Can't connect to Orion API at <http://0.0.0.0:80/api>. Check that it's accessible from your machine.

Can't find any help on internet besides doing

prefect config set PREFECT_API_URL=<http://0.0.0.0:80/api>

Any ideas ?

It should work if you set PREFECT_API_URL to the externally-visible address of your server (with

/api

still added to the end). The UI will pick that up when it starts, and then when you load the UI it will use the correct address to contact the API.

You're welcome! Glad to hear it worked.

Actually it did not worked completely, now when trying to create a work queue from the UI, we have this message :

Error occured when trying to create new work queue

I haven't seen that one before. Do any errors show up in the browser dev tools console?

@Ryan Peden Yes, we found that there is a 405 response for a request to

<http://xx.xx.xx.xx:4200/xx.xx.xx.xx:4200/api/work_queues/>

. We use this dockerfile to run the server :

FROM python:3.9.16

RUN pip install prefect prefect[aws]
RUN prefect config set PREFECT_API_URL=http:/xx.xx.xx.xx:4200/api
CMD ["prefect", "orion", "start", "--host", "0.0.0.0"]

Hi @Ryan Peden, do you have any ideas on that matter ? Thank you very much

I will take a look today - that looks like it might be a bug. If so I'll open an issue and see if there's an easy workaround.

Thank you Ryan, I hope you'll find the issue 😄

Thanks for the follow-up! It's easy to miss that typo; I didn't notice it either. When I set up my local test environment, I just typed in the address for my own machine, so I didn't catch the missing slash in your URL.
