OTAA accept not received when in reach of multiple gateways

the join-JSONs on MQTT looked quite complete except for the one case, where there was a nonce error message

Then I’d assume that you’ll get all errors, including Activation not valid - no gateways available when applicable.

Yet another aside: if your tests are getting you a lot of “Activation DevNonce not valid: already used” then this might help:

A workaround from @htdvisser on Slack, if you really need to clear the nonces that TTN has stored:

The backend clears the DevNonces when you change the AppKey, so if this is a problem, you can just change the AppKey to something else and then change it back
