OTBR Web service is not started?
I'm following the steps here: https://openthread.io/guides/border-router/build to install OTBR on a Raspberry Pi 4.
At step 5 where one issue the command "sudo systemctl status" the documentation mentions that the otbr-web.service should be started. This not the case for my 2 attempts do perform this.
The sudo systemctl status is to check the status of all servies. Did you mean 2 attempts to perform all the steps (1-4) ?
If otbr-web.service wasn't started, did you try the final bit in step 5:
otbr-web is enabled by default for most platforms If otbr-web is not installed, try passing the WEB_GUI flag: ....
I wasn't aware that the WEB_GUI flag wasn't on by default. I have later been made aware that one need to set that flag.
I believe the default for WEB_GUI is 1 for all the example platforms:

Maybe the setup scripts are not properly capturing your platform?
Not sure. I'm using a Raspberry Pi 4 with Raspberry Pi OS (latest).
