Can't see logs properly in QGroundControl

Hi all.
I recently tried downloading some old logs, but my QGC Log Download screen shows this:

I am unable to download the logs as well. When I try to download a log, the ‘status’ column of the selected log changes from ‘Available’ to ‘Error’.
My hardware is Cube Orange (on standard carrier board) running on PX4. QGC version is stable (I tried Daily Build version, but with that, I wasn’t even able to connect to the pixhawk).

Any help would be great.

Thanks in advance!
