We have used the Cloudfare loadbalancer to manage a pool of webservers and distribute requests to them.
Normally all is ok.
but over the past week we have been experiencing a problem which means that quite often we see a 404 message come back from a web service call.
So, if we do a web service call to the cloudfare load balancer, we get regular 404 errors.
However, if we do direct calls to each of the web servers - we don’t get any 404 errors at all - on any of the servers.
I’ve been checking the configuration of the load balancer and it all seems ok - it certainly hadn’t changed preceding the errors appearing.
Is there anything logical I can check ?
