- 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 22.214.171.124
mail.<domain> A 126.96.36.199
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.
