Venus OS 2.93 and 3.0 no Access on Node Red "400 Bad Request"

Hello together,

I want to update my old Venus OS 2.82-Large-30 to the newest possible Venus OS version on my Raspberry 4. The Venus OS 2.82-Large-30 run fine and the Node Red works also fine on port 1880
But I want to have my system up to date soon.

For the installation, I use a new SD-Card, so i made a new clean Installation. After writing the Venus-large 2.93 image on the card, I start the setup on the GUI of Venus OS, I activate also the Node Red service over the menu point "Venus OS Large features" I got the message that the Access to Node Red is now possible under port 1881. A different port as on my old 2.8 installation!

When I try to get access over this port (1881) "http://192.168.179.50:1881" I get the message on my browser window: "400 Bad Request The plain HTTP request was sent to HTTPS port nginx/1.16.1"

I tried also the Venus OS version 3.0 with the same result!

Does anyone have any ideas to solve this problem?

@Rittschie

You need to connect using a secure https connection. This has been changed with the new firmware. See also: Accessing Signal K and Node-RED

Thanks a lot!

I don't know why I didn't come up with this idea? :-)
