Hello,
I was able to get this sorted out by editing the IP=92s in the database. Af=
ter I edited them so the engine could reconnect to the servers, I simply re=
moved them one by one and re-added them to the engine dashboard. So far, th=
ey are working as expected.
psql engine -c "update vds_static update host_name =3D 'newIP' where gatewa=
y =3D 'oldIP';"
After, it complains about the networks being out of sync which is OK. Simpl=
y reinstall the host =96 I had to remove them one by one first, add them ba=
ck, then I was able to resync the networks without issue.
Should this be used, always make a backup of the engine first.

Yes, but then that DNS becomes a very bad SPOF for your system, so not
a good idea for a production systems...
