Hello,
I was operating under the impression that you were restricted to using the zipped update sites for installing extensions.
I checked for Palladian update zip but found per [1] that there was not one.
Installing the Palladian nodes via their update site [2] went without a hitch.
But, if you can use KNIME AP from the zip archive (thus skipping installation issues) and access the update sites normally (via internet) then you should have zero problems installing any updates.
Can you verify that you’re using AP 4.3.0 and that you’re using the right update sites/zip files?
What happens if you try a fresh “install” (zip unpack) of AP 4.3.0 with a clean (new) workspace and nodes installed via the update site (not zip file)?
Regards,
Nickolaus
