Nifi: The supplied username and password are not valid when accessing it from remote machine

[#1]

Hello All,

Hello Everyone,

I installed nifi on a linux server under /opt/nifi_server/nifi. I can connect to nifi using the provided passwords, but when I try to access it remotely, the error "The supplied username and password are not valid" appears.

Earlier, it was working fine.

I started facing issues when I removed the NIFI folder, re-extracted it to the same location, and started the services.

Any assistance would be greatly appreciated.

Thanks,

Shakib

Good day, everyone. 

This problem has been resolved. I made a new subfolder called /opt/nifi_server/ and installed the NIFI in it. When I first began, it gave me the error "Unable to bind the IP with port 844." I terminated the PID and launched the Nifi.Everything is back to normal now.
