Calendar won't finish loading
- 
 I have put in a url (webcal://calendar.google.com/…/basic.ics) 
 And the calendar will not load.
 I am running on a raspberry pi b+, so maybe it is because node is outdated?
 Any ideas?
- 
 @johnpturner8 Have you tried to access the ics file straight from the pi (through a browser maybe)? Would be the first thing I would test. To see if it can even reach it at all. 
- 
 @EoF It wouldn’t connect to the webcal:// address, but when I replaced it with http:// it downloaded the file. I tried replacing it in the config files but it still won’t load 
- 
 The default calendar didn’t load either, so it may not be the url. 
- 
 Please note that Raspberry Pi 1 (any version) is not supported. The software on them is just too damn old. You might be able to run MM¹ on it.

 @KirAsh4 I’ve gotten it running in kiosk mode, but the calendar might not work on it. If it doesn’t I’ll just get rid of it.
