Hey all, I keep getting the following error when trying to deploy a prefect flow:

The above exception was the direct cause of the following exception:

An exception occurred.

I am using prefect v2.20.2 and docker v27.2.0 I have checked my docker is working and this image is available for me to pull manually. Not sure why I keep getting this error?

I was also experiencing this this issue and never found the cause or a proper solution. Switching from Docker Desktop to OrbStack fixed it for me.

Hmmm interesting. I remember I had this issue a few months ago and reinstalling docker resolved it but not even that is working now. Thanks for your tip. I will try OrbStack

Daniel, are you located outside of the US? I'm asking because my coworkers and I figured out that this issue only happens when we try to create a deployment from Europe. If you switch location to the US (e.g. with a VPN) the issue goes away. 🤯 I've created an issue about this: https://github.com/PrefectHQ/prefect/issues/15928. Hope we can get it solved because this has been VERY frustrating to debug. /cc @Bianca Hoch if you can get some eng eyes on this we would greatly appreciate it! I'm available if any other info is needed regarding this!

Ah interesting. Yes I am outside the US - based in Europe. Very odd that it works only from the US! Thanks for creating the issue
