A few days ago (2015-12-05) changed the certificates for all our services/domains on one - more secure.
This does not affect the operation of any service.
The problem may have only some users of Unix systems when using the tracker. Errors returned by the tracker, their description and solutions see HERE.
Our current certificates are always available HERE. Thereby feel free to use secure connections using SSL,
that is, humanly speaking HTTPS in the address.

On Your request, by the end of the year, we run the promotion -50% on all packages in the donations shop
