I'm using WHS 2011+SP1. Never any problems, great software BTW, saved my neck a number of times. Have 5 clients here at home!
The good news is I have complete control/access of everything. The bad news is I'm not sure what you suggest I do.
By "re-install WX" do you mean install WHS 2011 on a clean disk. I can do that but it would be a real pain, In fact I think I have to first install WHS 2008 and then the upgrade -- not sure. If the problem is access to the 8080 port is there not a command line to see what ports are open.
On Acronis, in the past I used/relied on that as a secondary backup -- mainly for complete disk re-installs. However recently I got badly burned because it would not re-install windows 10 on a system that went down. In MHO the Acronis team are not what they used to be in terms of customer help -- numerous complaints on the web. My preference now is WHS for nightly backups and W10 disk image for a complete screw-up/disk crash.
