There is yet another issue with nvidia drivers and indirect GLX, which
will generate almost the same error message. Indirect GLX was disabled
by default in Xorg 1.17, which was introduced in Centos 7.2 and 6.8.
This problem only happens if you run the GL application remotely and
display on nvidia driver enabled screen. It's not clear from the OP
if that is the case here.
The solution would be to add +iglx to Xorg command line, but gdm is
hardcoding the Xorg parameters, so if you use gdm/gnome you are out
