Hi All
setting up a headless Zynthian with a raspi 5
I have installed and cannot connect to the webconf
when I set it up on a 3 b+ it worked fine.
I can connect via ssh so the ip address seems to be resolving correctly but the webconf won’t connect
I get ERR_CONNECTION_REFUSED
I have tried with chrome safari and Firefox all the same.
any pointers of things to try?
thanks
J
Does webconf fail on the ip address in the url?
yes both the ip and the zynthian.local fail
you say you can ssh to the machine (as zynthian.local?)
is there anything in …
/zynthian/zynthian-webconf/cert
there should be two pem files.
Looking at the logs via ssh might give a clue as to why webconf is not available. Please ask if you don’t know how to do that or where they are.
yes there is cert.pem key.pem

is this what you are looking for re logs?
Yes, and it looks like Zynthian is busily trying to get a display working, and of course since you’re running headless the problems make sense…
Since you can’t run webconf; Could you use an editor to change the configuration file(s) to indicate you don’t have a display?
I can’t remember details of the filename-format - I think you can find prior in this forum.
Is there something I can edit to tell it what to do?
so I have got /zynthian/config/zynthian_envars.sh
open should I alter this line?
export DISPLAY_NAME=“Generic HDMI/DSI Display”
if so what should I call it headless?
That’s not one of the choices in webconf. I haven’t done this myself, but let’s try:
export DISPLAY_NAME=“Custom Device”
and see if that gets you into webconf.
unfortunately not still getting the same error.
Really appreciate the help.
could we see the new logfile?

Methinks we need someone who actually runs a headless Zynthian to share how…

ok cheers really appreciate help!
there is the file /boot/firmware/config.txt. Simply add:
hdmi_force_hotplug=1
hdmi_drive=1
hdmi_mode=27
dtoverlay=vc4-kms-v3d
video=HDMI-A-1:1280X800M@60D
This programs the HDMI ports to talk to an HD-ready monitor with less framebuffer size than 1920p and less CPU time for drawing. There does not need to be a monitor connected with force_hotplug to allocate the display framebuffer and start rendering graphics to the output.
amazing thank you that has sorted it!
