FabScanPi Server is currently not running

Hello everyone,

the last days I started working with the FabScan.. including the assembling as well as the software installation. I'm right now struggling with connecting to the FabScan Server. I already recognized that this i a common problem but I couldn't find any answer so far during my research. Whenever I try to connect to the server's ip address, the server is currently not running.

Checking the server leads to the following message... saying that it's active...

pi@fabscanpi: $ sudo systemctl status fabscanpi-server
