Since 2.8.0 RC1 --- The Piwik URL does not seem to be pointing to a Piwik server

Hello,

nothing changed in server setup, worked great before, then I upgraded to Piwik 2.8.0 RC1 and the cron isn’t running anymore with following error:

INFO CoreConsole[2014-10-24 12:22:26] [622ae] ---------------------------
INFO CoreConsole[2014-10-24 12:22:26] [622ae] INIT
INFO CoreConsole[2014-10-24 12:22:26] [622ae] Piwik is installed at: https://example.com/_stats/index.php
INFO CoreConsole[2014-10-24 12:22:26] [622ae] Running Piwik 2.8.3 as Super User
ERROR CoreConsole[2014-10-24 12:22:27] [622ae] The Piwik URL https://example.com/_stats/index.php does not seem to be pointing to a Piwik server. Response was ‘ 404 Not Found

Not Found

The requested URL /_stats/index.php was not found on this server.

’.

The only “strange” thing I see is, that the “requested URL” points to /_stats/index.php which is not the full path on the server, or it’s missing the domain name.

I have found some similar problems regarding the error message here in the forum, but none of them helped. And like I said, nothing changed in the server setup, just updated Piwik.
Now I am running latest Piwik 2.8.3 and the same problem. Any ideas?

Edit: Forgot to say, I am trying to run archiving:


 /usr/bin/php -f /var/www/vhosts/example/httpdocs/_stats/console core:archive --force-all-websites --force-all-periods=315576000 --force-date-last-n=1000 --url=https://example.com/_stats/

try over HTTP instead of HTTPS maybe? also check the URL returns the piwik login form

Piwik works normally, just archiving gives me this error, http or https, same.
And like said, it worked before very well.
I was hoping, someone knows if they were changes regarding archiving in 2.8 RC1 and where I could take a look.
