Moved 2 Domains to another server now they wont show anything

I moved more than a week ago 2 websites to a new Server. DNS Settings are fine but both pages only show error 500 or a blank page. I moved everything correctly and it was done in half an hour, I’m educated and working as IT. My Provider wont stop blaming cloudflare, and as far as I know I have a lot more projects setup in the DNS settings of those 2 Domains, and they are working flawless. So I’m kinda in a bad spot right now. My Provider blames cloudflare and wont do anything anyway, can someone help me resolve these issues? It’s for following domains:

https://metal-schweiz.ch
https://gerber-web.ch

It’s not acceptable that these pages are almost since 2 weeks down and noone cares…

For now, use the overview page and “Pause Cloudflare on site” and see if you can get those two sites working. That will put them in DNS-only mode so you can troubleshoot. Just give that setting five minutes to take effect.

Alright I’m currently trying out your suggestion. I wanted to write you that a traceroute command to www nad non www adress results in nothing, Cloudflare isn’t processing my dns entries for sure. Here are the results:

I will report back later if your suggestion has worked…

So i moved the DNS entries to freeDNS and now its being resolved correctly… As it seems, but the pages are still blank but i guess its no cloudflare related topic anymore so, case closed.

But let me know what the problem with cloudflare not forwarding my entries is and i will change back by then I was happy with using Cloudflare.
