I’m surprised the nightly is running such an old version, I’ll open an issue about it.
Do you see any useful logs from the influxd process when you hit the server errors?
I believe only influx setup writes to /root/.influxdbv2/configs, everything else is stored by the influxd process. I’d still expect that data to end up in /root/.influxdbv2, so you see any other files in that directory, i.e. an influxd.bolt?
