When I setup Grommunio I left it as DHCP and added a reservation on the DHCP server. This seems to mess up the hostname on reboot/DHCP renew as it reverts to the shortened name. I can manually set the hostname from the CLI with hostnamectl but is this enough? Should I just use a static IPv4 address?
Everything has been working fine with this setup but in the last few days I've been plagued with autodiscover issues that get resolved with a reboot - nginx-autodiscover-error.log 228, 426 & 455 upstream timed out, 610 & 273 no live upstream while connecting to upstream.
I've not troubleshot too deeply so far as a reboot has quickly fixed it but it feels like maybe an update has changed something and the hostname/DHCP issue is rearing it's head.
