I have some workflows (for example, the workflows developed by 3D-e-Chem) that use this nodes and now i can’t use this because in the installation files are not included.
Hi @ocasanova,
are you having trouble installing these extensions, you probably do not have the Experimental community extensions update site enabled. Take a look at the community extensions documentation page, it explains how to enable that update site, then your extensions should work again.

Hi, thanks for the answer.
Are you referring to Nightly Builds???
because in another case I have enabled the Community Contributions (Experimental) and when I install the extensions I mark all of them.
I see you are using downloaded jar files instead of the online update sites, maybe they are not up to date?
Can you try using the online update site?
best,
Gabriel
Thanks again for the answer.
I use the last .zip available and the version 4.0.2. The problem now is that when I put the trunk file or Nightly Builds (.zip) and execute the installation, after restart, KNIME open and all views are white and don’t work any view and report several problems.
I can’t use the direct url because my university use a proxy server and I can’t use the online form.

That is disconcerting, can you please send us your knime.log files?
Did you try entering the proxy information in the KNIME AP preferences? Then you should be able to use the online instal.

Gabriel
Hi, gab1one
Thanks for your answer again
Here there is a picture showing how it look like.
And the log file is here
knime.log (2.6 MB)
About the internet connection when i start KNIME, ask for authentication and in this point I ask Is sufficient with that or not?

Did you try starting KNIME AP with the -clean option?
Are you installing all available extensions from the nightly update site, or just the ChEMBL ones? If the former is true, try only installing the ChEMBL extension, confirm that it works and then add additional extensions as needed.
best,
Gabriel

Thanks for your answer
Using -clean options don´t solve the problem. I solve installing KNIME 4.0.1 and installing the nodes from the Community of the 4.0.0 version (Community Contributions and Trusted Community Contributions). Nightly builds continue without work properly.
But when I try to connect directly to the site through the proxy I have this errors
Some sites could not be found. See the error log for more detail.

I transform in Edit/Preferences/General/Network Connections to connect and say that errors.

Hi @ocasanova,
I investigated the ChEMBL extension and it is not available for KNIME 4.0, as the authors did not update them for 4.0.
You can however take a look at the following components:
You see how to access ChEMBL without this extension.
Regarding the proxy, it seems like the configuration is not correct, I know from personal experience that the proxy setup is prone to mistakes.
best,
Gabriel
