On attempt to turn on Firewall for VPS server via CCPv2 the following message appears in panel:
"Failed to perform the operation, please try again later or contact administrator."
At the same time, browser console logs the message below:
"[IM] An attempt to create a duplicate object. Please double check your data"
As the result, firewall is not activated.
The cause of this behavior are duplicated firewall rules, which are contained in APS resource of affected VPS. It was found that duplicates are inserted upon VE recreation if Plesk Panel is installed. Such behavior has been recognized as software-related issue CCU-14675.
Please contact your Technical Account Manager or a member of PTA team in order to track the status of CCU-14675. In order to apply workaround for this issue please contact Odin Technical Support.
