I recorded this strange bug after updating to the latest PS3 update (4.41). I had to then update my Playstation Store and encountered this:
Now I have a Netgear R6300 AC now enabled with Beamforming + (It's what they call it). I'm also using Sophos UTM 9, so nothing is blocked, but filtered for protection here. On the second try, it worked.
So as the download was approaching 100 percent, it continued past 100 percent to 300 percent and timed out. Strange indeed. The link above is what I captured from my Android S3 and I uploaded it. Has anyone else encountered this?
This also happened when I updated Mortal Kombat to the latest version. Not sure why the download runs past 100 percent.
The Web Caching feature in Sophos UTM 9 caused this bug after extensive troubleshooting. I disabled it, re-downloaded the updates, and it was applied. There is still some research to do with the Web Caching feature enabled...the PS3's web performance is enhanced with the Netgear R6300.
