Cannot read from device (Invalid medium data format.) DP 9.08

I recieve error as below when medium is writen, the media agent (AIX server) via fiber cannot read the keys for decrypion.

When I deactivate drive based encryption or when medium doesnt have protection everything works fine,

Does someone has solution about this issue?
