Nodered version 3.0

Hello
I'm a beginner on Nodered and I can't connect my remotec on Nodered, I receive the following message"you must be logged in to deploy changes and " could not fetch nodes.

Thank you

Welcome to the forum @daak.

You need give us more information.

What is a remotec? A URL to the product would help.
What do you mean by "connect it on Node-red"?
Apart from remotec issues, does Node-red otherwise work? What device is it on?
Where were you and what were you doing when you received these messages? Screen captures would be good.
