Hi Pierre,
found the problem.
Actually, it was just a
sun.security.provider.certpath.SunCertPathBuilderException (see below).
A simple
-> sudo dpkg --purge --force-depends ca-certificates-java
-> sudo apt-get install ca-certificates-java
and everything was working again.
"Network is unreachable" on the UI just put me on the wrong track.
*Once again, thank you very much for your support, Pierre.*

Hi,
I just tried and I can properly fetch the data for both URLs using
InvokeHTTP. I'd really suspect something specific for the node/host
where NiFi is running.
Thanks,
Pierre

Dear community,
I use InvokeHTTP to access various websites.
When doing so, I get the following error for some URLs:
InvokeHTTP Request Processing failed: java.net.SocketException: *Network
is unreachable*
The same URLs work fine in the browser or with wget at the same time.
Examples of these URLs are:
-
https://www.idaireland.com/latest-news/press-release/sanmina-announces-expansion-of-ireland-manufacturing-site,-creating-up-to-150-jobs
-
https://www.phonearena.com/news/motorola-is-flirting-with-the-idea-of-phone-you-can-wear_id175252
I only noticed this error after upgrading from NiFi 2.4 to NiFi 2.6.
I use Ubuntu 22.04.
Does anyone know what is causing this?
Is there a new feature that I overlooked?
Regards,
Kay-Uwe
