here's a recent trace
domain is altersmoke.gr
Unfortunatelly I don't have more information to give you at this time, it just happens randomly, it's like having a momentary downtime, if you hit refresh the site loads correctly.
I've also encountered it on mobile
Hosting company can't help me, they say everything is good on their side, and I tend to agree because I paused CF for a week on the domain and we haven't encountered any such problems.
hosting company is Hetzner

In my case, took forever to find it but I managed to fix it by turning off http2 to origin toggle on cloudflare under domain -> speed -> optimization if anyone needs it in the future.
does your origin not support http/2 ?
Yes it does and it was (and still is) enabled. So, i believe there was some kind of conflict between cf and my host.
