Hi community I'm using the StandardOauth2AccessTokenProvider to get and refresh a token, which works great. But almost at every refresh, one of the nodes in the cluster gets this error. It's not the same node which gets the error every time, all nodes gets it but only one node at a time.

So I can't see if all nodes in the cluster is refreshing the token at the same time, or if it's only the primary nodes which refresh. If all nodes are refreshing could it be that one nodes is slower than the others to refresh, and that the old tokens gets invalid after the first node has refreshed it? Kind regards Jens M. Kofoed
