Hello, this lab is not working: https://kodekloud.com/courses/docker-swarm-services-stacks-hands-on/lectures/5974046
Could you please take a look at it?
Thanks for reporting!
We will fix it
Thanks, none of the labs are working
Just click on a lab item, no text is shown or lab is loaded.
Can you please share a screenshot? and share this one also, after clicking on this link katacoda.com/embed.js. Let me know what you’re seeing.

Can you please try from different browser?
It looks like it is working in Safari
Try to clear the caches or use icognito window and it will work fine
Yes, correct. Thanks
