Hi All, I've got a debian stretch box running ispconfig 3.1.13p1 - and all the websites hosted on this system are using cloudflare proxying. This system hosts a few low traffic sites. In the last few months, I've noticed an issue where if you don't access a website for a long time, then try to access it, cloudflare will give a timeout. But if you reload the page, everything works just fine, and continues to work fine for the rest of the "session". The error.log for the offending site says this: 2020/01/17 14:22:39 [error] 29193#29193: *29966 upstream timed out (110: Connection timed out) while reading response header from upstream, client: 188.8.131.52 Its almost as though if the site isn't accessed for a while, it gets paged out, then serving it up for the first time takes too long so cloudflare calls it quits and gives the users an error message. But once you reload, it works fine (until such a time as the site hasn't been accessed for several hours/day(s) - then it starts again). This only affects to affect sites that use php (wordpress etc). We've got a few static sites (just html/css) - those seem fine. For now, I've setup a cron job to access the site every 5 minutes to keep it "live". Any ideas on how to fix this permanently?
