We have a VPS running a big multi-site platform. This platform is using cloudflare for Ddos protection and load balancing, URL is www.112barneveld.nl.
The problem is that since this morning cloudflare is giving the error:
We debugged the whole VPS and not a single error is found. What could be the issue? It started happening 8:49 GMT+2 today and since than the site goes on- and offline from time to time.
We are clueless right now. Any help is appreciated, thanks in advance.
