SunCertPathBuilderException

When I try to log in, I get the following error which can be seen in screenshot. SunCertPathBuilderException: unable to find valid cerfitication path to requested target. I tried reinstalling Java. I also disabled Windows firewall and ESET firewall.

I marked launcher version 1.2.3, but I cannot select actual version 1.2.5 here, as seen in screenshot.
