Hello,

I was able to get this sorted out by editing the= I=3D P=3D92s in the database. After I edited them so the engine could reconnect = to=3D the servers, I simply removed them one by one and re-added them to the eng= =3D ine dashboard. So far, they are working as expected.

psql engine -c "update vds_static update ho= st=3D _name =3D3D 'newIP' where gateway =3D3D 'oldIP';"

After, it complains about the networks being out= o=3D f sync which is OK. Simply reinstall the host =3D96 I had to remove them on= e =3D by one first, add them back, then I was able to resync the networks without= =3D issue.

Should this be used, always make a backup of the= e=3D ngine first.

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