Just today, OpenHAB Logviewer stopped working. The error is …
Firefox can’t establish a connection to the server at 192.168.1.xxx:9001.
This has worked since installation early last year. I did not change anything in the system setup or configuration. Only changed items, things, and rules during normal development work.
How should I proceed to troubleshoot / fix this problem. I am forced to open a terminal to access the logs.
If restarting the service does not work, another option is to try reinstalling frontail using openhabian-config menu option 21. There were several changes to the way frontail works recently so that could be the issue.
