if it becomes more intricate you might want to use mtr (traceroute) from
the client end with the URL that caused the error. It will give you a
list of all the network nodes involved. Then you have to ask each of
them whether they have an issue with the request. It could be a size
issue or some nasty webwasher that identifies the image as something

It might become more intricate still, if there is a firewall involved
that blocks the trace routing. Good luck.

Best regards,
