Your node has been disqualified, re-qualification?

No, only a held amount from the satellites which disqualified your node.
However, if you didn’t opt-in for zkSync, your undistributed amount may not clear a minimum payout threshold on Ethereum (L1), therefore, your final payout may be delayed either until the fee for transferring it is lower, or until your remaining nodes collect more undistributed amount (if you use the same wallet in your next nodes).
So, if you prefer to receive your undistributed amount earlier you may opt-in for zkSync.
