Can't get the Mikrotik LR8 connect to TTN

There is no point registering with two different systems as you can only tell the gateway one place to send the uplinks without getting in to rather advanced settings, v2 & v3 traffic are shared between the two and one will be shut down in the near future.

Have you read the sticky note at the top of the forum about v2 console status?

v3 only shows connected once it see traffic.

Please can you format you post, see this for info:
