In the TTN console ‘General settings’ for the gateway, is ‘Require authenticated connection’ set to ‘Enabled’? If so, remove the check mark and save and wait a couple of minutes. Forget about the serv\_gw\_key, it is not being used by the software that uses UDP on port 1700.

@studhsruhrwest if you are still stuck, try adjusting the server\_address as follows

> “server\_address”: “eu1.cloud.thethings.network:1881”

n.b. for me, I do need to have the serv\_gw\_key : Gateway Link API value  
but perhaps that is something to do with using port 1881 (I’m not sure)

That is because you are running MP forwarder which uses port 1881. Kerlinks don’t use that software and do not use that port nor the serv\_gw\_key.

No, it isnt’t set to Enabled. But i also tried it with set to Enabled. Both not work.
