Extensions not available?

[Jakobfelchner]

Hi all,

as I am new to KNIME I am not sure if this is a problem caused by the program or caused by my missing knowledge. I try to install extensions but by trying to open the extension page in KNIME I always receive the error message shown in the screenshot below. Is there anything I can do to get this clear again? Thanks in common..

Hi @Jakobfelchner , could you tell us which version of KNIME you are using and on what OS.

Are you using KNIME on a corporate network, possibly with a firewall or proxy server that might be blocking access to the KNIME update site?

If you click on the this link, do you get a “forbidden” message (like below), or something else?
