Blocking Cross Origin API request

NOMAD and FAIRmat
1

Hello,
when launching north tools, the tool will produce a log saying something similar to [W 2025-02-08 17:43:47.427 ServerApp] Blocking Cross Origin API request for /nomad-oasis/north/user/<user>/fiji/desktop-websockify/. Origin: http://<ip>:<port>, Host: <ip>. For instance, when I try to use Fiji, I get redirected to a Jupyter-Lab-like page which says Status: **Failed to connect, giving up** . I guess this is because of the Cross Origin API request-blocking. Is this a common problem or a bug in my Nomad-Oasis?
Thanks for your help!

Hi @kaikoebnick!

I have not heard about this exact problem before, and cannot reproduce the problem in our production deployment. But this sounds like some type of a problem with the proxy setup. I will check if anyone from our side is aware of this type of a problem.
