When I try to login to Garanti Internet Banking, I get a message that says “The internet site you are trying to view uses a certificate that was signed by an unknown authority. This page cannot be displayed” . What should I do?
The browser you are using is Internet Explorer version 3.xx. It is not possible to login to Garanti Internet Banking with these versions as these browsers are not compatible with the security systems that we use. To safely use Garanti Internet Banking, you need at least version 4.xx of Internet Explorer installed on your computer.
The reason you get this message in Internet Banking or Mobile Banking is that you have entered your PIN incorrectly for multiple times.
The reason of the problem is that the root certificates of the Verisign company installed on your computer have expired.
