The error Error at line 13:Expected [-3], read [58] suggest there’s an error at this line, but I can’t see what:

DTSTART;:20191103T150000Z

Using DAVx⁵ version 2.6-ose (308)

[rfc2822]

@otiel Hi,

This line is not valid. If there is a ;, it means a parameter will follow: DTSTART;paramname=value:20191103T150000Z. In your case, there is no parameter.

The line should be: DTSTART:20191103T150000Z instead.

Does that help? How did you create this event?

[otiel]

@rfc2822 Thanks.

I’ve created the event using the SOGo web app, nothing special as you can see on the screen capture below.

I’ve seen that SOGo is on the list of tested services, could it mean that my provider has “tampered” with the SOGo setup? What’s my options there, contact my provider?

[rfc2822]

Is it this problem? https://sogo.nu/bugs/view.php?id=4802

Does setting a time zone (probably for the system/user) help?

[otiel]

Yes, exactly! I had not configured my timezone, thus it was UTC by default.

After setting my timezone, events now sync correctly. Thanks a lot @rfc2822, problem solved.

For those having the same issue, go to Settings > General under SOGo web app to set the timezone:

@otiel Thanks for the update!
