Gateway V2

I am unable to connect new gateways to V2.
I can register the gateway but no connection.
Tried different server addresses.

Is this prohibited because of V3?

Not yet… your problem will be elsewhere - provide details and forum may be able to help/point to issues…

Ok what is the correct server address for EU?
In the gateway i see an address that starts with router.eu.thethings.network

On the TTN console i see eu.thethings.network

Which one is correct?
