Hi Capuderg
I have heard back from the hosting company (HeartInternet.co.uk) and this is their reply
‘This is a loopback error on the server.
Our servers prevent scripts making HTTP (port 80) connections back to the same server that they’re running on, as policy.
This is done to prevent the possibility that mis-configured scripts could enter, essentially, an “infinite loop”, making call-backs to themselves. Such a situation is extremely detrimental to server performance, and would negatively impact other users also on this shared server.
Unfortunately we are not able to lift this block on a per-site or per-scriptbasis, so you will need to see if you are able to reconfigure the script (or contact the script authors for assistance doing this), or use an alternative script that doesn’t require HTTP requests to its own server.
Alternatively, you could use the full URL to connect to the peer.’
Could you tell me how to fix this error?
Thank you so much!
