Just to put this out there just in case anyone else runs into it… I followed the basic format of the .env.example for generating the auth keys. However if a key gets generated with a space (which I did not notice) you need to wrap it in quotes…
This fixed my issue so hopefully will help someone else who didn’t catch this detail.
I ran into the same issue running the install on MacOS and the issue was because of the ‘localhost’, simply replacing this with ‘127.0.0.1’ resolved the issue.
