Sorry work arounds are not working for some of you. Work arounds do work for evidently some and myself (in Texas) See Unable to Connect to Companion with AI Companion
The following ameliorate the MIT server issue (for some)
- check Use Legacy Connection on Companion before scanning the QR code
- using the emulator. Yes it works.
- using the USB connection option
- using the MIT code.appinventor alternative server also is affected.
- compiling your app and testing. Tedious but several users say it works.
MIT is trying to fix the issue going so far as to replace existing server hardware. This may take some time. Please be patient; eventually the server will be back to normal.
The issue for some of you may be your existing Project having issues. You can test this by creating a simple Project (place a Button on a form) and using Companion with Legacy checked.
