My contract inactive too. The support answer me.

Thank you for contacting Mintsy. My apologies for the downtime. This is a known issue with our Scrypt contracts which are currently under maintenance. Our developers are aware of this and are working on a fix. Please allow some time for them to resolve this issue. Rest assured this is being worked on and your worker will be back online shortly. Once back online your workers will be compensated with more hashing power than promised in the contract.
