Hello, after prefect 0.12 release I have this kind of bug. Can anyone help me?

Hi @Rafal! Does the environment in which you're spinning up Prefect Server have any networking restrictions?

Not sure what are you talking about, but I do not about any restrictions 🙂

Ah, gotcha. Some environments like AWS have the option to restrict outbound traffic. I thought maybe that was the cause of the error you were seeing. 🙂 Can you share the version of prefect you're running? I'm unable to replicate this issue.

So, it's the latest for sure
