Hello everybody! My colleague (@Greg Roche) and i tried to update our self hosted prefect server (on EC2) today (from 0.14.15 to the latest version - 0.15.5). After updating prefect we tried running the server but we saw already some errors in the console. We were still able to connect to the UI and we saw that all the connections to

:4200/graphql

were refused. After some trying we gave up and downgraded back to 0.14.15 again (it worked again but we lost the data - flows, flow runs etc.) - no big deal. I was curious and thought if connections were just refused it shouldn't be too difficult to get it running - so i created my own

docker-compose.yaml

file from

docker prefect config

and changed some values. I ended up changing the interfaces that the services are listening on (graphql,apollo,ui) to 0.0.0.0 - after that it worked again. This makes it impossible for us to update our prefect server 😞 I couldn't find anything in the

prefecthq/server

repo that could cause those connection problems (at least from the most recent changes) - could someone please look into this? If you need any more information please let me know 👍 Thanks in advance!

Hey @Tim Pörtner, I think this is related to some breaking changes with 0.15.5. Check here . You might need the

--expose

flag to enable remote connections. Server would also need to be upgraded to 2021.09.02

thanks for replying and thanks for the info! reading the release notes could have saved us some time 😅 thought it was a bug because the ui was accessable without any changes

No problem!
