Job history

HI,

We have BE 20.5 and and a Tape library.

This morning when open the BE 20 console I can see my jobs but the section of the job history showing loading and no data. also when go to the storage I can not see my library slots.

We did restart the BE services 3 times but still the same issue.

Any suggestion?

Thanks

UPDATE,

When click on loading get this error:
