Need Immediate Attention and Resolution

Hi Team,

Accidentally the Octopus\OctopusServer folder got deleted and its a production server.

Machine Details :
OS : Windows Server 2012 R2 Standard
Octopus Version : 2.6.5.1010-x64

In the program files, I can see the octopus instance is not deleted.

We have a octopus deploy database backup available. And tried to restore its asking for the Master API key which we did not make a note of it. Kindly help me out to fix this issue ASAP.

Regards,
Latha.
