Are you familiar with Mikrotik’s RouterOS?
It is not as easy as the configuration of a FritzBox!
Perhaps you can check first wich Server are configured on your LoRa interface.
As i remember in default configuration there are only eu.mikrotik.thethings.industries and the “us.” variant configured.
You must edit one of these entries or add a new one to:
router.eu.thethings.network
Up port: 1700
Down port: 1700
You can olny edit these entries with the LoRa interface disabled.
It is hard to get it debuged this way.
Perhaps it makes more sense with (nearly) full configuration dump.
As you are using winbox, go down the left hand menu and peruse the selections until you find “terminal”
Then in the terminal window type:
/export hide-sensitive file=configname.txt
and hit enter.
Then go back to the left hand menu and select files.
You should see the file you created on the list of files that shows.
Right Click on the filename to download it to your PC.
