Hi There! I have tried to upgrade the main router, and I receive a

400 Bad Request​

This server does not support the operation requested by your client.

I tried rebooting the device several times without success. Any advice?

I upgraded a few days ago and haven’t run into any issues so far. Thanks for your contribution!
