Hi Joe I just found out that port 6342 is bound to localhost. Why???? In the last build NIFI is bound to localhost as standard if not specifying which interface to use: nifi.web.https.host=node1.domain.com nifi.web.https.port=8443 nifi.web.https.network.interface.default=ens192 <----- If this is not configured the UI is bound to localhost.
But how can I configure port 6342 to bound to any interface??? kind regards Jens Den tor. 10. jun. 2021 kl. 16.32 skrev Joe Gresock <jgres...@gmail.com>: > Ok, and just to confirm, you've verified that each node can talk to the > others over port 6342? > > On Thu, Jun 10, 2021 at 10:29 AM Jens M.
