It Keeps saying this it let me code my arduino last night but I woke up this morning and it didn't let me code this anymore how can I fix this and I do still have the app installed. Its happened some many other times but only at my house.


Did you purchase a subscription via the Chrome Web Store or from Arduino as an educational institution?

In any case, I've tested both scenarios and they both work for me.

There might be an HTTP proxy on your network that is causing this issue.
