This error occurs when there is a problem with an IP in one of the services located in ESXi firewall.
The IPs entered into the GUI will all look correct and you have exhausted all possibility.
The root cause is usually that you have entered individual IPs in CIDR format with a /32. ESXi does not like this.
How to correct the problem:
1) SSH to the ESXi host and edit /etc/vmware/esx.conf
2) Remove the /32 from all IP entries for the firewall (see below). Be sure to leave all larger CIDR annotations in place (/24, /27, /28, /16, etc.)
3) Reboot!
/firewall/services/webAccess/allowedip[0000]/ipstr = “192.168.10.10/32” <- Bad Entry – remove the /32
/firewall/services/webAccess/allowedip[0001]/ipstr = “10.10.20.0/24” <- Good Entry

1. Truncate your databases
Truncate your databases using this command:
/opt/vmware/vpostgres/current/bin/psql -U postgres -t -d VCDB -c “select ‘truncate table ‘ || table_name || ‘ cascade;’ from information_schema.tables where table_name like ‘vpx_hist_stat%’ and table_type = ‘BASE TABLE’ order by 1” | /opt/vmware/vpostgres/current/bin/psql -U postgres -d VCDB
2. Make sure to tick the box to export your performance data

VMware PowerCLI – How do I add functions?
When first using VMware PowerCLI, you will need to add functions that are associated with your profile.
Create a new profile:
PowerCLI> New-item –type file –force $profile
Once your profile has been created, you can now add functions by typing:
PowerCLI> notepad $profile
The above command simply opens notepad and allows you to edit your profile directly.
Once you have added functions, you will need to reload your profile (or restart PowerCLI):
PowerCLI> .$profile
