Starting 28-July-2012, I see the following entries in the KC warning log once a day:
[28/Jul/2012 xx:xx:xx] License update failed: Automatic license update failed during attempt to contact registration server: (11) Unexpected server response
[29/Jul/2012 xx:xx:xx] License update failed: Automatic license update failed during attempt to contact registration server: (11) Client-Server communication error.: couldn't connect to host
[30/Jul/2012 xx:xx:xx] License update failed: Automatic license update failed, when getting information from registration server: (11) The license number is not valid. Please, check your license number and try to enter it again.
[31/Jul/2012 xx:xx:xx] License update failed: Automatic license update failed, when getting information from registration server: (11) The license number is not valid. Please, check your license number and try to enter it again.
[01/Aug/2012 xx:xx:xx] License update failed: Automatic license update failed, when getting information from registration server: (11) The license number is not valid. Please, check your license number and try to enter it again.And so on, every day.
It looks like Kerio Connect starts calling home to check the license, it has not done that up to and including versions 7.3.
Once a day or on every restart of KC, it tries to contact the host register.kerio.com (= 195.113.184.8 as of this writing). It tries to POST to URL https://register.kerio.com/registration/LD.php. The user agent string is "Kerio License Downloader (LicenseManager)".
If you want to block KC from calling home, you can add a line to your hosts file:
127.0.0.1 register.kerio.com
Or you can block the IP address in your firewall.
I have not seen any effect on this, KC is still fully functional as of this writing, but this might change after a month or so is over. I will update this thread with any news.
That's right, but I didn't started this topic and I only react on the last sentence of the starter of this topic (....I will update this thread with any news....). I had the same messeages on KC but it changed as I wrote in my response.
Since a few days now this message appears:
License update failed: Automatic license update failed. User interaction is required by registration server.
Still KC works, but just in case I have downgraded my other production server to 7.3.3
If you have a valid license for KC 7.4 try to register it manually with the registration vizard. You should not be forced to downgrade if you have bought the product. If that doesn't help, open a support ticket with Kerio.
Nice
