Calendar not sync in nextcloud 13?

[ricardos]

Hi

My server (nextcloud 13) is OK, but since a few days calendar and contacts are not syncing with davdroid.
Is there any known issues?

[devvv4ever]

No known issues currently. Since a lot of people use DAVdroid with NC we would know if there is something broken. You can post your logs/debug infos here and we can take a look at it.

[ricardos]

Everything was working ok for the last year but now suddenly the sysnc is not working.
In the app there are no errors but when i create something in the phone it’s not synced to the nextcloud and vice versa.

It’s only me?

[ricardos]

I have no errors
which logs? from nextcloud or there are any produced by davdroid?

@ricardos said in Calendar not sync in nextcloud 13?:

ontacts are not syncing with davdroid

[rfc2822]

Please have a look at https://www.davdroid.com/faq/how-to-debug/

We’re using NC13 with DAVdroid ourselves and there are no problems…

[ricardos]

Can anyone see anything wrong here
It’s not syncing with nextcloud 13 server (last stable version)
I don’t understand what’s happening

[rfc2822]

Please provide steps to reproduce, Web server and Nextcloud logs taken while the problem occurs, DAVdroid debug info and verbose DAVdroid logs etc as described in [READ BEFORE POSTING] What’s required to diagnose a problem.

[RedCider]

I can confirm this.
Nextcloud 13.0.0
DAVDroid Version 1.10.1.1-ose

Downgrade to Version 1.9.10-ose fixed the Problem for me though.

It seems to be a problem concerning timezones:

[rfc2822]

@redcider Can you please provide the full debug info and the contents of the remote resource mentioned in the debug info? Without this information, there’s no chance to find out what’s going on.

[encryptor]

Hey guys, I’ve got the same problem and I can provide you with some more information.

This is the debug output. I have replaced the following:

• my personal email address with “user@server.com”
• my tld with “myserver.com”
• my name with “encryptor”
• my real calendar-titles into “cal”+“one/two/three/four”

https://paste.fedoraproject.org/paste/ZFYKyFwdahNFhNLcozOMpw

This is the log output of my nextcloud server. I have replaced the following:

• my ip-address with “127.0.0.1”
• my name with “encryptor”
• my tld with “myserver.com”
• my (one and only active) calendar-title into “caltwo” (The error occours to every other calendar as well. I just wanted to keep it short)

https://paste.fedoraproject.org/paste/1Vi05fksu2X4s5E1G02zhA

And this is the same output, but I have inserted some whitespace and shifted some lines to get a better overview of what’s going on. You can see, that davdroid doesn’t support the right username two times, so it results in an “attempt”. And the third try supports the rigth username and then it’s successful.

https://paste.fedoraproject.org/paste/DYWr5LvO0MDUO741uz5BRA

Regarding the timezone, I have set up my nextcloud config as this: https://paste.fedoraproject.org/paste/ZJW6i2zPxAOFkdmp9ffSiw

Does this help you? What else do you need?

Thanks a lot,
Encrypor

I have sent the latest beta version via email to check if the problem still occurs with it (there have been related changes).
