NIFI SSL Invalid Host Header error with port forwarding

comviva — Thu, 25 Jan 2024 13:30:42 GMT

We have a nifi cluster of 3 nodes on which we are implementing SSL. All the configuration changes are done but when we access NIFI UI on our browser It throws this error -

System Error
The request contained an invalid host header [127.0.0.1:<port>] in the request [/nifi/]. Check for request manipulation or third-party intercept.
Valid host headers are [empty] or:

Our port forwarding is like this -

ssh -L 18443:<node-1-ip-adress>:8443 -i ~example.com
ssh -L 28443:<node-2-ip-adress>:8443 -i ~example.com
ssh -L 38443:<node-3-ip-adress>:8443 -i ~example.com

Then our ssh tunelling via putty is like this -

L28443 127.0.0.1:18443
L48443 127.0.0.1:38443
L58444 127.0.0.1:58443

Any ideas how to resolve it ?
