Hello,   I've looked everywhere and can't seem to find any posts about resolving this issue. I set this same type of config in Google Cloud and it works fine. However, something is wrong with our configuration in our environment and I can't seem to figure it out but I think it's some type of bug. Any suggestions are appreciated.   Here's the scenario: Overview:    We have a nifi cluster (2 nodes), we have enabled all of the Site-to-Site settings on both nifi nodes.   # Site to Site properties nifi.remote.input.host=abcd nifi.remote.input.secure=false nifi.remote.input.socket.port=1234 nifi.remote.input.http.enabled=true nifi.remote.input.http.transaction.ttl=30 sec nifi.remote.contents.cache.expiration=30 secs   However, the minifi-app.log keeps getting the following errors when we try to start the flow. 2020-12-14 19:19:19,595 INFO [main] o.apache.nifi.controller.FlowController Not enabling RAW Socket Site-to-Site functionality because nifi.remote.input.socket.port is not set 2020-12-14 19:19:19,595 INFO [main] o.apache.nifi.controller.FlowController Not enabling HTTP(S) Site-to-Site functionality because the 'nifi.remote.input.http.enabled' property is not true   However, if I look at the RPG in Nifi, it doesn't show any error saying that the site "is not configured for site to site communication". If I change the nifi.remote.input.socket.port to 'ABC', then the RPG in the Nifi UI shows the error message "not configured for site to site". Therefore, it seems as though Nifi knows it is configured for site to site but minifi doesn't believe so. I am seeing some communication between Minifi and Nifi via the nifi-api but nothing for site to site. Therefore, the main question is what would make minifi not recognize that the nifi RPG is configured for RAW site to site communication?   Another odd issue on the Nifi side is that when I create an RPG and an Input port and then I try to connect a GenerateFlowFile processor to the RPG, I get an error stating that "no input ports are available". We have 2 other environments plus my GCP environment that does not get that error when I do the exact same thing. We have gone over the Nifi node settings to try to ensure that clustering is setup properly and we think it looks good and other process groups are working fine (that don't use RPG's). We've restarted the nifi services multiple times. Another note is that we have the Java Minifi 0.5.0 running on Windows and the Nifi nodes are Linux.   Please let me know if I can provide any other information. ... View more
