IP changing for the subscription over API fails with the error:
Unable to update hosting preferences. Failed to updated ip. Can't set to addon domain ip different from webspace ip
This issue occurs only when there are subdomains created for the domain and when changing IP address at once with one of the following settings:
- Hosting settings
- Hosting php
- FTP user name
- FTP password
The same issue occurs in OBAS on Plesk 11.5.30 and 12.0.18 nodes.
