Hi @ajith-ramawickramagm

I have pulled a new instance of the course that seems to work fine now. It is the course-introductory-workshop course and I have renamed your old instance to be course-introductory-workshop1.

Can you let me know if this works okay for you? Thanks!

Hi @megan_mcp it works now. Thank you. Just curious to know is there a workaround that I can troubleshoot this myself in the future

You can do this same action by renaming the old course and clicking the "Launch KX Sandbox" button again through the course page.

Hi @ajith-ramawickramagm

Are you running the notebooks within edu.kx.com?

Hi @mmcparland. Thanks for your reply. Yes I am. Just clicked the "Launch KX Sandbox" button here https://academy.kx.com/courses/kdb-developer-level-1/lessons/course-introduction/ and it redirects to the edu.kx.com

Okay great. I’m going to access your server to try and mend the issue.

I will update when all is resolved, thanks!
