IMPRES Battery Fleet Management: Not Connected to Database

If you are running IMPRES Battery Fleet Management on a Windows server, you might come across this error when opening the Battery Fleet Management web page (user interface).

The page loads normally but the Connection Status is Not Connected to Database. It should be saying  Connected to Database. In this case, there were no errors during installation and all updates were installed. Both Windows Server 2022 and Battery Fleet Management are running on a Virtual Machine.

It turns out that TCP port 8080 is blocked by default on Windows Server 2022 (possibly even other versions too). Unblocking this inbound port on the server (Windows Defender Firewall) solved the problem.

The page content is requested and served on TCP port 80 - which is not blocked. This would make the page load but always with the above error. Unblocking TCP port 8080 clears it!

If you look after a number of MOTOTRBO portable two-way radios and use IMPRES batteries, Battery Fleet Management is an excellent tool to keep track on how all these batteries are doing and will save you money. Read more about it here.
