Voila rendering ipywidgets in one system but not in other system

I have created a dashboard using ipywidgets and trying to render it on voila. It runs perfectly on one system but not on other. On the other system plots are rendered but not widgets. I have updated all the packages on both systems. The only difference is port. 8888 is workingit but on the other system 8890 is not.

If the problem persists, I’d say to create an issue in Voila’s repo.
