Help! Apache - Init: Unable to read pass phrase

I attempted to resize my main disk. I took a backup snapshot then increase it, everything seemed ok. Unfortunately upon reboot apache refused to start with this error message:

[error] Init: Unable to read pass phrase [Hint: key introduced or changed before restart?]

Full error log:

So I restored from the snapshot and I'm still unable to boot apache, same error message. Googling around results in vague messages about ssl certs not having a pass phrase set or that the pass phrase isn't being read on boot (?). No idea, but I don't see how this issue could persist after a backup restoration.

I'm at my wits end here, any help?
