Ok. But...

Maybe the cloudflare server is much stronger and so creates a DOS 
attack. Isn't there a 'nice' option at Cloudflare?

Do you use an Apache? Then you can tweek how much clients and requests 
it allows at the same time. For example:

https://httpd.apache.org/docs/2.4/mod/mpm_common.html#maxrequestworkers

https://httpd.apache.org/docs/current/mod/mpm_common.html#maxconnectionsperchild

Maybe the HTTP server configuration is not the best and it allows 
clients to crash it.

Alles Gute
