Can't license device OTA

I can license my ESP-32 device over USB, but not OTA, as follows:

Step 1 Successful license via USB

C:\Mong\Orchard97>mos license
Connecting to the device…
Using port COM3
Querying device UID…
PID: mos UID: 0f178ca5e71b36d3

Updating config:
device.license = kqPNu5zO4Aic8NvYLnataldvtTea6sKdorWUHGg/m3YCstGsXhClNi3+7uDJbTWvSrlTUKVmrBFu0cf1/kdJNVEE8kK+qyTeZbSQXblk3IsypJc3TYprK07ivO8Yt6KS4TlwteFQeTW9nsz8ffewTDUr6qwKdoLfjiwSFCE4raCCWT6Ls5b7GCnXaWE95Kzp
