I am running into this Certificate Error Navigation Blocked at a .gov website. the address is https://sdo.gsfc.nasa.gov/data/aiahmi/ & https://sdo.gsfc.nasa.gov/ .I use the site everyday & I was wondering if I am the only one with this new problem(October13-14-15now). I used IE11 & Google Chrome & had the same results. Windows7 Operating system. This "fix" did not work. (Under "Security", uncheck the boxes "Check for publisher's revocation" and "Check for server certificate revocation.")
Thank you. The next step is trying to inform them. Maybe I'll get through the oppositional forces & reach someone via my Twitter @IAmNotTheClone or my email.
