Well, this hardware should be more than sufficient.

Another day, another log search.

Once i use a non SSL connection to the Mailserver i get some more log errors from z-push.

Mainly 3 different error messages on first sync

06/10/2021 21:40:35 [87856] [WARN] [daliane.klein] /usr/share/z-push/include/mimeDecode.php:352 Undefined offset: 1 (8)

the obvious error message that this is now a plain connection even thou it is going via localhost ;-)

06/10/2021 21:40:28 [2213332] [WARN] [daliane.klein] Unknown:0 Unknown: SECURITY PROBLEM: insecure server advertised AUTH=PLAIN (errflg=1) (8)

Sometimes i see the following

mimeDecode.php:352 hints to a message which has an “multipart/signed” part, but there seems to be an issue with the handling - I have seen this before, but it has not been relevant for me.
imap.php:1449 is a result of the error above.
caldav.php:841 replace the line with:

$message->reminder = $interval->format("%i") + $interval->format("%h") * 60 + $interval->format("%d") * 60 * 24;

(There is a fix in the PR for ZP-1571 but it has not been merged yet.)

“icc not configured” and diffstate.php:230 might be the result of renaming a folder, this is not implemented. I tried implementing this, but I still have some issues with the devices states.

imap.php:1128 there is a check missing, I will try to get a PR through…
I have to look into the timezone error message…

maedball

@bob4os As usual, thanks for your help already. The fix -> fixed the issue ;-).

I think my main issue is the issue related to the multipart /signed (sounds like SMIME to me). I just did a full sync and found several thousand error messages related to this.

maedball

@bob4os Seems like the fix will cause all my birthdays (automatically created by nextcloud based on contact data) to not sync. So maybe it is still not the final fix ;)

bob4os

If you did change line 841 in caldav.php in this block:

elseif (!array_key_exists("VALUE", $parameters) || $parameters["VALUE"] == "DURATION") {
    $val = str_replace("-", "", $property->Value());
    $interval = new DateInterval($val);
    $message->reminder = $interval->format("%i") + $interval->format("%h") * 60 + $interval->format("%a") * 60 * 24;
}

then it has nothing to do with nextcloud birthdays.
These lines are only there to set a reminder (notification before event) x seconds before the event.

Your Nextcloud birthday calendar should be a separate collection (calendar) - it is with mine.
What did you set for CALDAV_PATH and CALDAV_PERSONAL in backend/caldav/config.php?

maedball

@bob4os Ahh nevermind… The nextcloud 22 upgrade killed the birthday calendar. I had to recreate it by enabling and disabling it.
Now i see other strange things, can you check if you have something like this aswell? (seems like you are also sporting nextcloud and z-push.)

Nextcloud

Outlook

bob4os

Should be a wrong timezone.
What timezone is set in your php.ini and what’s the timezone in your Nextcloud settings (personal information)?

bob4os

Can you download the the birthday calendar entry and post the content of the ics file here?

maedball

@bob4os Sorry it took a while:

Nextcloud
-> German

Z-Push config

    define('TIMEZONE', 'Europe/Berlin');

Php.ini
Has nothing set -> everything is commented

I don’t know why but it seems like in outlook it is taking 1 am for the start and end which is why i see it across two days

bob4os

I have my timezone set in php.ini too.
Try setting it to ‘Europe/Berlin’, restart the PHP service and you probably have to resync the birthday calendar - disabling and enabling it again in Nextcloud should do the trick (just check that the calendar disappears in Outlook).

maedball

@bob4os Does not change a thing. What is really frustrating is that it is working for some entries like sarahs but not for Petras. I am not sure if this is related to some of these error messages above.
The problem is that i have way to many of these error messages and need to get rid of some of them to point problems to specific error messages. I started by tracking down some of these but it really takes a lot of time to link a problem to a specific mail or calendar entry.
