I use the following procedure with ansible.

1. Setup the server with the things I need for k3s to run
2. Setup k3s
3. Bootstrap and create all my services on k3s via ArgoCD

@A_A Thanks for letting me know about the issue. I ran into the same issue with my gmail, but it worked with every other email I had, so thought it was just a one off.
I will look more into it. See if switching to a different email provider fixes the issue.
