Vmwaredisks resource failed

vmwaredisks resource keeps failing with a log error " Failed to decrypt password " 

Although the password didn't change from VMware side. what we do : 

-Hit vcsencrypt -agent command and type the actual password and then take the encrypted output password and replace it in the main.cf file.

-After some while the same error keeps popping up for some reason. 

So any opinions?
