SymptomsPlesk Panel utilities that use .NET providers sporadically fail with the error similar to the below example:
> ftpmng.exe --install-vhost --soft --vhost-name=domain.tld.
ftpmng.exe exited with error code -2146234327.
CauseError code -2146234327 is related to internal .NET timeout. It occurs during the failures in finalization process inside Operating system.
The error normally does not occur several times in the row. It should not bother you again in case if you repeat the action which led to this error.
ResolutionJust repeat the action in Plesk Panel which led to the error.
In case if the error does not disappear after repeating the previous action, please contact Parallels Technical Support for assistance.
