Syncing stopped working

[dmolineus]

I use to synce ICS files from two different sources. One source from outlook.offfice365.com stopped working, reproducable on two different devices (Last sync was on 19. August, maybe related with update to version 2.3.1). The ics file generated by outlook.office365.com is accessible on the browser and other clients though.

Bug still exists on latest version 2.4.0
