Hi! Could you tell us please, what to do in our situation? At least where to go and what to check? We have been using NiFi 2.0.0 M2 for half a year and yesterday suddenly we opened it and got an absolutely clear canvas. Flow files in /conf/archive/ dir are very old and they have the same size as the flow file in conf/ dir. They contain nothing. Could this problem be a consequence of the expired SSL Let's encrypt certificate? It expired at the end of September.
Thanks in advance! -- Best regards, Anton Granik
