: i/o timeout

Hello, i have a problems with heartbeat. It's work normally before and now very often shows down( : i/o timeout ) but internet's is good if i tried open sites manually is too open good. I don;t understand why heartbeat all times show down with comment (: i/o timeout). Please help

Have you tested from the same machine at the same time with curl? It's likely that there is a problem with your connectivity given that error.

yes, of course i tried. i think i don't have a problems with connectivity because i checked it and everything is good
