WARNING[4105][C-00000001]: app_rpt.c:6308 rpt_exec: Cannot find specified system node xxxxx

Hey good morning/afternoon/night

Suddenly two ASL3 nodes stop connections due WARNING[4105][C-00000001]: app_rpt.c:6308 rpt_exec: Cannot find specified system node 596489

One thing, the node cannot find is the it self on both cases

Never touched both, one have a Dell Wyse 3040 and the other in HP CoreI5.

Why ?

Thanks
