Yes, the error relates to making requests to itself, which means any attempts to connect to any (custom) API endpoint will fail. So, it’s defintely a major issue.

I’m getting these messages in Site Health:

Unfortunately these prevent me from continuing my projects using DevKinsta, because I can’t connect to any of the APIs I created. (And they work fine in DevilBox – which is also a dockerized solution for creating local environments)

I’m curious, since I’m on Windows 10 Pro, and @slaFFik is also on Windows 10 Pro, is it a W10P specific issue?

Edit: it seems to be a specific issue for WordPress running in a Docker instance, I found these links. Maybe it’s a good idea to pass them on to your devs:
