I setup a proxy and it worked in Knime-Workflow-Nodes like GET, etc. But the update und extension-installer seem to ignore these settings. The Node-Recommendation also dont works and get no list. Any suggestions for these (aside the zip-installation)?
From another topic I assume you configured your proxy settings within the KNIME preferences already, correct?
Can you please share your knime.log from within your workspace directory (knime-workspace/.metadata/knime/knime.log)?
