I am setting up a second HA instance at the same location, a ‘production’ instance and a ‘backup’ instance, both running on separate RPis. Everything seems to be working except Tailscale on the new HA instance. Tailscale does work on the original HA instance. I loaded a full backup into the new HA which included Tailscale and have updated all software. The error when starting Tailscale on the new HA instance is ‘[supervisor.utils.json] Can’t write /data/addons/data/a0d7b954_tailscale/options.json [Errorno: 2] no such file or directory /data/addons/data/a0d7b954_tailscale/tmpnq9x4637’. I ‘logged in’ and there isn’t a /data directory on either HA instance. Under HA settings/addons/Tailscale/configuration I selected logging level ‘trace’ and attempted to start Tailscale. Under the log tab it displayed ‘No errors have been reported’. The error above is from the supervisor log on the new HA system. Also, according to info from google, I may need to setup the authentication URL, though I expected that from the full backup. I changed logging on the ‘production’ HA instance to trace and can’t find an authentication URL. Guidance would be much appreciated.
I solved the problem by uninstalling and re-installing Tailscale. Working properly now.
