Nexus repository not accessible from Talend TAC

We are using nexus 3.35.0-02 and Talend TAC
After I choose releases and click on “Apply”, I get the 500 error regardless of what I enter in GroupID field or leave it empty:

I can browse and download every component in my release repo on UI.
We have also verified our credentials and it’s OK.

Hi Safus,
This screenshot does not look like Nexus Repository - perhaps you’ll have more luck looking for help from people around Talend instead.
