I downloaded a fresh install of Local and am still getting the same errors, “Local detected invalid Docker Machine TLS certificates and is fixing them now.” followed by "“Uh-oh! The requested site ID does not exist in local” when trying to select sites from the left sidebar.
This error, “Local detected invalid Docker Machine TLS certificates and is fixing them now.”, seems to be stuck on repeat as I’m getting them every 5 seconds, over 50 total in a few minutes.
I’m definitely seeing the errors that you mention in the Local log. That usually means that Local is having problems generating the necessary credentials to communicate with the Virtual Machine.
Because of the nature of this sort of thing, there isn’t one specific fix, so you might need to try a few different things, including reviewing any VPNs that you use, or other networking software that may be interfering with Local’s communication with the Virtual Machine.
