minor correction - the port shown (8543) was from the alternate port test, the regular port test 8443 returns a similar error: " Nifi fails to start, with the log saying: 2021-08-20 18:55:27,715 WARN [main] org.apache.nifi.web.server.JettyServer Failed to start web server... shutting down. java.io.IOException: Failed to bind to /35.xxx.xx.xxx:8543 Caused by: java.net.BindException: Cannot assign requested address"

I'm aware v1.14.0 requires a user login when not using certs, but I can't even get to that step. I'm pulling my remaining hair out trying to connect to a new Debian VM on GCP running v 1.14.0 on Java 8. Nifi starts and runs properly, with this caveat - I cannot reference the static external IP - only the default IP (127.0.0.1), so my browser can't connect. I have a GCP firewall rule that opens the 8443 port for the VM, and even added ICMP to it and can ping it from a CMD shell on my PC. I've checked all of the file permissions on that VM, all uniformly correct. Details of my nifi.properties: If I use: nifi.web.https.host=127.0.0.1 (the default) nifi.web.https.port=8443 Nifi starts properly and runs, but my browser returns " 127.0.0.1 refused to connect " If I use the VM's static IP (which is what I've used on prior VMs): nifi.web.https.host=35.xxx.xx.xxx nifi.web.https.port=8443 Nifi fails to start, with the log saying: 2021-08-20 18:55:27,715 WARN [main] org.apache.nifi.web.server.JettyServer Failed to start web server... shutting down. java.io.IOException: Failed to bind to /35.xxx.xx.xxx:8543 Caused by: java.net.BindException: Cannot assign requested address Endless web searches and tests have resulted in no change of behavior - with the default IP, Nifi runs but I can't access it, and with my external IP, it won't start. I've even tried using a different port (8543), no change. In this GCP project, I have just this one VM and it has successfully been running Postgres for many months. Any ideas? Mike Sofen
