Actually, I can figure out what to do based on this (the screenshot just helps sometimes). What I need to know is what your geographic location is, in order to report the problem.
In general though when this error pops up, there's a temporary server problem somewhere that you're intermittently hitting. Cloudflare is pretty good about noticing these problems and fixing them, but if I can file a report indicating what geographic location you're accessing the site from, it may help them zero in.
I'd ask for other technical stuff, but given the "elitaret" thing, probably too troublesome.
