Media uploads acting weird after tightening WP Cerber settings — could it be related?

Hi,

I’m seeing some odd behavior on a WordPress site after making a few stricter changes in WP Cerber Security, and I’m trying to figure out if it’s connected. I edit and download from here the videos and then upload the final files through the Media Library. Lately, uploads have been a bit inconsistent:

  • sometimes they take much longer than usual

  • sometimes they seem to go through, but the file doesn’t process properly (no preview, missing info, etc.)

  • and occasionally nothing happens, no clear error

This didn’t happen before I tightened the Cerber settings, so I’m wondering if something there might be interfering with uploads. Has anyone run into something similar? Or is there a specific log/setting I should check to confirm if Cerber is blocking or filtering these requests?

Thanks in advance.
