Just yesterday my second AP is showing disconnected in Alta control. Self-hosted on version 1.0h. Although it is connected as I can ping it. It’s connected in mesh mode to my main AP. Even when I plug it diretly into the switch it still shows disconnected. I have recreated the docker container and reset both AP’s. Basically starting from scratch but to no avail. If I only have 1 AP connected it connects but no longer seems to like the 2 together. Any ideas
Welcome to the community 
What happens if you go to the IP address in the web browser to the AP not connected?
I think you can try the following:
/etc/init.d/rc stop
echo http://local.12345678.ddns.manage.alta.inc > /cfg/domain.txt
rm /cfg/rcapi.txt
/etc/init.d/rc start
Make sure you put your actual server address 
It also might be worth trying another browser to see if it lets you access the Basic Web GUI
Thanks, that sorted it. Still don’t have local access to either AP but at least the controller is seeing them both now. Thanks for your help
It’s my pleasure
When you say local access? The webGUI disables once it connects to the controller
Thanks, get you now. So the local web access for the AP is only accessible whilst it isn’t connected to a controller. Appreciate the help, glad to have it all working again. I was previously all Ubiquiti gear, but really loving the Alta products, just keep getting better
Awesome news! Yeah any issues give us a shout!
