Hi
What is the error you have on Calendar on macOS? What did you input to connect? Are there any logs in the Davis logs (prod.log)?

I'm myself on Calendar on macOS, same standalone version and it works fine

[NxckyBear]

error on apple calendar is "username/password could not be verified"
Using the "manual" method, input the email address, password and the domain.
when doing so I get the 404 error in docker logs.
nothing in prod.log

I use barebone docker version but I use caddy as a reverse proxy. My bad for the confusion, I changed that accordingly.

And your server path is correct / ports are open on your reverse-proxy? Davis is returning a 404, not an authentication error, and " username/password could not be verified " seems like a client error, so something in your setup doesn't point to the correct path

[NxckyBear]

port is open as I can access the admin dashboard. How should I check if the path is correct?

If I use the extended login, it still gives me a 404 even tho I am using the path Davis is giving me, and the port I use on the reverse proxy.
