Hello Evereybody,
I’m having the following problem.
My calenders are not synchronising. I get en error message “HTTP Server error - HTTP 404”.
I’ve looked throughthe forum but haven’t found a solution that works for me.

My phone is Fairphone 5
e/OS version 2.9-a14-20250321478214-official-FP4
I’ve tried the following:
Removing and adding my account again.
Tried syncing manually.
Sync individual parts of the calender, Tasks, Personal, Deck:Personal.
I’ve tried disableing the VPN.
But everytime it fails.

I have no problems with synching my contacts.

Hopefully somebody has an idea.

Problem seems to be fixed, after some trial and error and experimenting.

  • Removed all of my Murena account form my phone (first saved all my contacts etc.).
  • Exported the complete calender from Murena.io (in the webbrowser on my PC) as a backup.
  • Removed all extra calender sets e.g. “deck:personal”.
  • Disabled the “task”, “birthday” and “limit number of events” functionality from the calender (in calender settings in the webbrowser on my PC).
  • After this added my account again to my phone.
  • Let is synchronise, and happy days.
