I can confirm that updating the site sees it hang/timeout without being able to load. So this is certainly the issue that you have described in the reply. I have since done the following:
I have root terminal access into my VPS ad have updated the TCP ports for both Bitcoin and Dogecoin adapters. I will shortly be adding my wallet servers ip to this list of open ports as well.
My next question is if the wallet server is offline (the location of my bitcoind which is other than my VPS), will the site still hang?
I am almost thinking its worth installing a trimmed node onto the VPS and removing all of the other admin of opening ports and IP addresses.
