HTML API /rr_connect?password=*** returns 404 Not Found

qurt

I do have a problem using the HTML API.
I have one board that always reply with 404 Not Found error when i call curl http://<ip_machine1>/rr_connect?password=<password>

curl : The remote server returned an error: (404) Not Found.
At line:1 char:1
+ curl http://<ip_machine1>/rr_connect?password=<password>

both machines have HTTP enabled.

M586 P0 S1                                                              ; enable HTTP
M586 P1 S0                                                              ; disable FTP
M586 P2 S0                                                              ; disable Telnet

calling other machines with works fine curl http://<ip_machine2>/rr_connect?password=<password>

Is there any other config that might prevent that behavior. I am not aware of significant differences between both machine types.

@qurt The affected SBC is outdated and does not support rr_ protocol emulation yet. Upgrade it using apt and then try again. See https://docs.duet3d.com/en/User_manual/Machine_configuration/DSF_RPi#installing-updates

Also note that it would be better to use the native REST protocol in SBC mode unless you need to deal with boards in standalone mode, too. See https://github.com/Duet3D/DuetSoftwareFramework/wiki/REST-API for further information.
