@sdetweil Oh my god, I’m so sorry I have to say this. It was all my fault. I had added an option to Nginx to limit connections to specific IP ranges at some point, and that took effect only after I restarted my server recently. My docker IP range was the only thing not listed, so everything else inside my network was working fine.

But anyway, thank you for helping troubleshoot, especially with your latest comment with all the debug! That was actually what helped me discover the issue, just not the way you probably intended!

All is good now. Thank you again 😭

@sdetweil Ah, so that was just to use the internal MM web server.

Yes I use Nginx for reverse proxying and I use a LetsEncrypt cert to add https. The https portion is working fine and I’ve tested the custom URL pointing to the ICS file using wget.

@sdetweil I’m not sure what you mean by “inside the MagicMirror folder”, but I created a manual location in Nginx that points to an ICS file downloaded from Radicale. Then I updated MM to point to this custom URL. Used Wget to confirm I can download using the custom URL. Same issue…

Then I removed the authentication from Radicale entirely, same issue…
Then I replaced the ICS file downloaded from Radicale with the ICS file from this repo. Same issue…

@sdetweil The URL I specified in the module will return an iCal file. It doesn’t have a filename in the url (which is confusing). Maybe I don’t understand CalDav/WebDav enough to explain it well enough. Or maybe this is a Radicale quirk.

Platform: Raspberry Pi 4
Node Version: v20.17.0
MagicMirror Version: 2.28.0 (running in docker)

I’m using the built-in magic mirror module for CalDav integration, but the mirror just shows “Error in the Calendar module, check the logs for more info”. Logs are below (personal info scrubbed).

My setup for Caldav is Nginx reverse proxy using Basic Auth -> Radicale instance. Auth is disabled on Radicale. I’ve triple-checked the password in the MagicMirror config is correct (even copy-pasted). When I manually browse the calendar URL, I get a Basic auth prompt, then I’m able to download the calendar as an ICS file.

Perhaps this wget log will help?
