Not enough memory to open this page

I need help on this from yesterday im getting the same message when I open my C1 W3 practice lab

It could be an issue with your browser or connectivity. Try switching to a different browser and see if that helps to open it.

I have tried in three different browsers it’s not helping

It is possible that the issue you are experiencing is related to your internet connectivity, as I was able to successfully open the same from my end.

There is some trick on YouTube. Just search Not enough memory to open this page on YouTube and hopefully, you will find some solution.
