I installed KNIME and it load but the recommendations aren't showing. I have a high-speed internet, no proxy settings and an exception has been added in Windows Defender. However, the knime.log shows an error and warning.

KNIME Extensions

I have a high-speed internet, no proxy settings and an exception has been added in Windows Defender. However, the knime.log shows an error and warning.

I have tried the below steps:

  1. Internet Connection: Ensure your internet connection is stable and active. KNIME’s Workflow Coach feature requires internet access to download the latest node recommendations and statistics from the KNIME Hub.

  2. Proxy Settings: If you’re behind a proxy or your internet connection goes through a firewall, it might block KNIME from accessing the internet. You can configure your proxy settings in KNIME by navigating to File > Preferences > General > Network Connections. Here, you can enter details for your proxy configuration, if applicable.

  3. Update KNIME Statistics Manually: From the details provided, it seems there’s an option to “Update Now” for the node recommendations statistics. If there’s an issue with automatic updates, try manually updating these statistics by clicking on “Update Now”.

  4. Firewall/Antivirus Interference: Occasionally, firewall or antivirus settings may prevent certain features of applications from functioning properly. Check to see if disabling these (temporarily) resolves the issue. If it does, you’ll need to add an exception for KNIME in your firewall or antivirus settings.

I am attaching the screenshot and the log file. Kindly help to resolve this.

Hi,
The log says that this file should exist but does not: C:\Users\User\knime-workspace.metadata\knime\file_download.temp
Can you check that folder while trying the update and check if anything is created there?
Kind regards

I followed above steps, but nothing seems to work.

Under knime-workspace, there are 2 folders, .metadata and Example Workflows.

Under .metadata, there are 2 folders, .plugins and knime. There are 2 files as well, .lock and version.

Under Example Workflows, there are 5 folders, Basic Examples, Customer Intelligence, Retail, Social Media and TheData. There are 2 files as well, .project and workflowset.meta.

I do not see the file you mentioned which is file_download.temp

When I click the button ‘Update Now’, the message I keep getting next to the same button is ‘Update Failed’. And the error message on top of the window reads as ‘Error loading the community node recommendations:update.knime.com. Please check your internet connection’.

But am connected to the internet as well. I completed an assessment, some videos and hands-on too so that error message about my internet connection is misleading.

Really not sure why this is happening. Any more steps I can follow.

Hi,
Sorry for leaving you hanging here. Somehow I did not get a notification about your response. Can you check the folder permissions of the C:\Users\User\knime-workspace.metadata\knime folder and all parent folders? Does the KNIME AP have proper permissions to read and write them? I would guess so, but it is worth a shot. Have you also tried downloading a fresh KNIME AP and trying with that? Your workflows will be safe in your workspace.
Kind regards,
Alexander
