Invalid authentication

[markusgg84]

I'am trying to connect nodeRed with my Home-assistant.

NodeRed V3.0.2
HA: 2023.6.1
Both are in Docker Containers on the same Host.

I've added the palette to my NodRed and have created an API Token with my HA User.
For Accessing I'am using the IP address of the host and the port 8123.

The NodeRed Log:
"Error: Invalid access token for websocket"

The HA Log:
2023-06-10 12:26:00.833 WARNING (MainThread) [homeassistant.components.http.ban] Login attempt or request with invalid authentication from 172.17.0.6 (172.17.0.6). Requested URL: '/api/websocket'. (None)

Do you have any idea what causes this Error?

Thanks in advance!

Found the problem, copied not the complete Token. Ctrl + A helped.
