Connection to Community Hub through Desktop intermittently stops working

Dear community,

I am writing this post to signal an annoying issue I’m facing on a regular basis.

My version of Knime Analytics Platform is the 5.4.4, and I run it on Windows 11 Pro 10.0.22631.

My company uses ZScaler for proxy management.

This is where the “fun” begins. I had to manually configure the proxy settings in Knime, using the actual proxy host. Sometimes, connection to Community Hub through the client will work like a charm, and sometimes it will totally refuse to connect and will just return this error :

There are no regular pattern for this error to pop.

Any idea of why this intermittence appears and how to solve it ?

Best regards,

Vincent
