When I click “Create App” on the MIT App Inventor website, it shows a “No available server” error. Can someone explain what’s happening? I have an assignment due soon, and I’m worried this issue might affect my progress or cause me to lose my work. How can I fix it, and why does this happen?
Hello.
Same here. Server in and out. I can’t work. Deadline is today.
This might be a server-side issue, but to better understand what's happening on your end, could you please check the browser console?
You can do this by pressing F12 → Console tab, then reload the page and see if any errors appear.
If you do see any errors, please share a screenshot of them here — that will help narrow down the exact cause.
The 503 (Service Unavailable) error means the server is currently overloaded and unable to handle requests. Since you're seeing this even on login/token requests, it's definitely a backend issue, not something on your side.
If both the main server and test/code servers are unavailable, it usually means there is high load or temporary downtime affecting all instances.
Unfortunately, there’s no direct fix from the user side. The best you can do is:
- Wait and retry after some time
- Avoid peak hours if possible
- Keep refreshing occasionally
Well, my best option this moment is going to bed. Still a lot to do. Thanks for the help. Good night.
Totally understandable — this is really frustrating, especially with a deadline.
Hopefully the servers stabilize soon and you can pick up right where you left off. Your work should still be safe once things are back online.
Good night, and best of luck with your submission tomorrow.
I'm continuing to look into what is going on here. We are running identical code on code2 without a problem. So I suspect I'm looking at something load-related.
I will be tuning some system parameters today in an attempt to improve things. Fingers crossed...

Any fix to this? I am getting the same message for my classes the past 2 days.
What time of day?
I'm about to deploy a new version with some tuning changes (nb204b-ai2a-1). It may help.
