January 29, 20251 yr My Tailscale is up and running, however, when I attempt to turn on Tailscale Serve, setting it to Serve, I get this error inside of the logs: Serve started and running in the background. Generating Tailscale certs! This can take some time, please wait... ERROR: Can't generate certificates!

January 29, 20251 yr Author That was it. I turned off the Tailscale DNS and it fixed the issue. Thank you for the help!

March 4Mar 4 @chris4michaels Can you please explain what you did to fix this issue? When you said you turned off tailscale DNS, did you mean to disable MagicDNS and HTTPS? Or you meant toggle them off and on?Regardless, I did what I mentioned above and I still getting this error when enable tailscale for my dockers.--------------Generating Tailscale certs!
