What does this error mean?

I keep trying to go to joann.com to buy some things, and I keep getting this message:

Below is the original error message

Error 101 (net::ERR_CONNECTION_RESET): Unknown error.

I have restarted my computer, I have tried to open it in different tabs. I know the websites good cause I can open it on my other computer. Any suggestions on how to fix this??

And I have a windows computer and I use Google Chrome!
