take a look into the logs (mainly openhab.log).
https://www.openhab.org/docs/tutorial/logs.html
and prvide the errrors/exceptions here (use proper formatting ).
screenshots are mostly not helpful.
and finally, openhab runs as a service and adds a listener to access the webui via browser. it is not a web service.
