I bought the elk node after I upgraded to eisy. I configured my elk node with 2 areas and the rest of the settings. 155 nodes were discovered. My programs started to work normally. After a while, I noticed my programs stopped working. I check a PIR for instance, it shows the details in IOX but when i move in front of the PIR and I can see it detecting me, the status didn't change on IOX. I can reach my elk and ping it. any ideas how to troubleshoot the problem?
