So first method didnt worked for me , the webpage never loaded, for the second one I copied the conf folder from c:/openems/config to the folder to the directory where the openems.jar file is located and then run the
this time when I ran Execute systemctl restart openems --no-block; journalctl -lfu openems , it does open like it was in the deployment guide but as you mentioned earlier with sudo systemctl restart openems. journalctl -lfu openems , this dosent run command gives errror on “-u , command not found”.
However even after copying the config folder , I see the same errors like " there are no schedulers configured" , " Uable to start modbus/tcp api on port  : cannot start listner " etc …
I am stuck in the same issue and also how can I see the GUI like I was seeing on my windows.
