Delay in archiving process

Since i moved piwik to another server i have a delay in the archiving process.

After I visit piwik for the firt time on a day, all seems to be OK, bute if i visit piwik again on the same day, it shows me the same data from the first visit. After some days the “old” data lokks like it has been updated.

timezone of server and php is set to Europe/Vienna and the timezone im mysql is set to system.

the only thing that works is to set always_archive_data_day in global.ini.php to 1 and then visit piwik again.
