"an unexpected problem (but not server timeout or http error) has been detected"
This is a frequent error I've been getting hit with while playing mkv files ever since I got a new a80k 4k Sony Bravia. It didn't happen on my very old 1080p Sony Bravia. At first I thought this might be connected to playing large (~18GB) 4k files, but this just happened with a significantly smaller 2GB 1080p file. Unplugging and restarting the Roku temporarily solves this.
This doesn't happen all the time and appears to be sporadic.
Are there any solutions to this that doesn't involve unplugging and restarting the Roku every time?
I've already seen other topics about this same error, but those threads have to do with specific channels (such as Disney+, for example). To my knowledge, none have been posted regarding the playback of video files.
I'm playing off a 5TB hard drive with the NTFS format.
I'm using a 4670 Roku Ultra with the latest firmware.
My connection and download speed are excellent, so I really don't see how this could be a network related issue.
