I’ve continued to work on this with no success. I have moved the domain to a permanent site (on https://xaymacacoin.com), in case CoinPayments.net was blocking the .gotdns.com domain. I also turned off my firewall temporarily. When I deposited LTCT transactions to my wallet site connected to CoinPayments, CP shows the updated balance, but once again, my site does not have the correct detail. Looking at the IPN history, it shows (again) that the IPN was not sent successfully. The IPN contents also have no errors at all – I’ve included a screenshot. 
Looking for any advice you can provide – this is really hamstringing my plans to get the site live.
I reply to all queries on the forums and via email, once per day, Monday to Friday (not weekends).
