Hi - please can you provide some more details rather than just an error message.

Hi, Knolleary…

I dont writing english very well but…

I build an architecture with Front End Node Red. The FRED server is configured on a vmware virtual machine with Debian 8 and the FRED client is configured on a raspberry pi 3. The settings.js file is configured for adminAuth authentication on the server and on the client but not is set to httpNodeAuth. When I initialize the communication, the error message presented in the debug is this:

“An error occured on connection with FRED server: ‘unexpected server response (200)’”  
“Maximum connection attempts reached. Cannot connect to FRED server: Talk to server”

Thank you…
