WOPI Discovery Synchronization timer job failing in SharePoi

Feb 27 2019 11:17 AM
Hi, We have observed that "WOPI Discovery Synchronization" timer job is failing some times in our SP2016 farm and the error message is as below:"The validation of proof token is failed and possible cause is that the issuer of the proof token is not trusted or proof token has invalid claims in it.. (Correlation=f7c0c39e-4b7b-7030-ce72-d31e993d74b6) "To fix this I have executed the "Update-SPWOPIProofKey" command and restarted the timer service and it got fixed....but after some hours again the timer job is failing and throwing the error. I have the below questions:1. How to get rid of this error permanently? 2. Since it is not impacting to any application ...and keep this as is unresolved ....will it impact anything to the server?3. By default this job runs in every 1 minute......so if we change the schedule to once in week ...is it recommended? and what should be the recommended schedule? Thanks&Regards, Habibur Rahaman MCSA,MCP,MCTS
