Environment

TKGi 1.18.5
BOSH 3.0.25+LTS-T

Cause

The Reserved IP settings in the Bosh Director tile - Network has an IP that is not usable due to it not being in the configured CIDR

IPs are reserved for VMs but since they are unresponsive Bosh cannot delete and reuse IPs or reclaim existing IPs.

Resolution

Update the Bosh tile in Network with the correct CIDR first of all, then update the Bosh cloud config with the correct static IP using below:

Store the current bosh cloud config with below command:

bosh cloud config > cloud.txt

Edit the cloud.txt file and update to add correct static IP:

...
static: [x.x.x.x]
...

Finally update the Bosh cloud config as per below command:

bosh update-cloud-config cloud.txt

Following this Apply Changes via the Bosh tile so the Bosh VM can recreate successfully.
