- Plesk 12.5 for Windows
The following error appears when trying to add subdomain:
Error: DNS record already exists.
In Plesk > Tools & Settings > DNS Template the following records exist:
mail.<domain> A 220.127.116.11
mail.<domain> A 18.104.22.168
This is a software issue with internal id #PPPM-4216 . The fix is considered to be included in future Plesk updates.
As temporary workaround you can remove one of
Plesk > Tools & Settings > DNS Template
and apply changes.
