The Server is Windows Server 2012 R2 and the B4J is being run on Windows10.
This morning (Asian time) I've made numerous (many, many) attempts to get it running, making changes to settings as found in numerous postings on the Web. Things that have apparently worked for others haven't worked for me.
I'm not sure I understand what you mean by "network access might be disabled". All my other network things seem to be working. I can connect to the Server using Windows Remote Desktop Connection. I can update the DB with a B4J program running on the Server so it has access there.
As I mentioned before, the only thing that isn't working properly is Port Forwarding but the strange thing there is that when I check I get an error on every Port, but my emails, browser and linking to other sites thru the browser work fine.
I'll attach a screen shot to show you what I mean about not recognising ports, though this isn't a real issue just at the moment and if the worst comes to the worse there, I'll go back to my previous provider.
I've just checked again that the program is working on the Server, and it does, interestingly it works with both the Maria driver and the MySQL driver.
Update 2 - Forgot to say that I can run a B4A app accessing a SQLite db on the same server
