Hello ​@mightystack 
That error is coming from Acuity, not Zapier.

“API had an internal server error” means Zapier reached Acuity, but Acuity’s system failed during the connection. This usually points to a temporary outage, maintenance, or an issue with your Acuity account or their OAuth service.

Try reconnecting after a few minutes, and make sure you can log into Acuity normally. If it keeps happening, contact Acuity support and share the error and time it occurred.
