Hello, I have a tagocore installation running and have integrated the first sensors from the TTN.
This also works, I would now like to establish the connection to tago.io at the same time. TagoCore is installed in the current version on a LINUX server.

I access the web interface via a reverse proxy. My access is therefore not http://ipadresse:8888 but: https://example.de this also works well and does not cause any problems.

I send my webhooks from TTN to: http://example.de:8000 

When I now want to connect to Tago.io, it stops at the last step - instance name. It does not continue here. You only see a red frame. Do you have a tip for me?
