certificate problem 5.26

hi all

Problem in the certificate

I used this lesson

http://wiki.mikrotik.com/wiki/Manual:Create_Certificates

But to be in error on browsers

Mozilla Firefox
This Connection is Untrusted

internet explorer
There is a problem with this website’s security certificate.

Please help

This is not an error. The browsers are simply stating that they cannot verify that the site is who it says it is. Just click through the warnings - the traffic will still be encrypted.
If you really don’t want to see this message, you will need to purchase a certificate from a trusted vendor (Google for ‘ssl certificates’).

thank you
