Can't connect to server to save progress

I’m new to freeCodeCamp and I’m trying to brush up on my HTML skills. I keep getting this error when I start doing lessons.

Try using another browser might somethimes help you. Chrome works best.

I can’t switch browsers because I’m using a linux machine with no root password. Firefox only :confused:

But, it’s linux you can just add debian or another one onto your machine? and play it from their it even can be runned from an usb

No. It’s not my machine.

I’ve got the same problem. Started last week, the error came up several times. I’m using Chrome on Windows 10. Just switched to Firefox, it worked. Switched back to Chrome and now it still works.

There’s something funky going on, but the workaround seems viable.
