Hi @Rafal - That error message looks like it's trying to connect to your localhost but you mentioned you're using cloud. Quick check to begin with - have you tried setting 
prefect backend cloud
?
If that doesn't work, can you give me a bit more information about your setup?
r
Hello Jenny
I just following official tutorial
From prefect docs, regarding registering flow on cloud
j
Thanks @Rafal - can you let me know which tutorial? Is it this one: https://docs.prefect.io/orchestration/tutorial/first.html#write-flow.
And double-checking - did you try 
prefect backend cloud
?
r
prefect backend cloud
works! I am following tutorial from side bar, which is accessible from prefect cloud page. There is no information after installing conda env with prefect and generating token to swich the backend
j
Great! Thanks for the update. And good point about the tutorial - I'll add a note for that.
Small update made. Thanks for pointing it out - hopefully your comment will help other new Prefect users.
r
Thank you @Jenny 😉
