I have been running Plex on my Synology DS918+ for approx. 8 months with NO issues.
Suddenly when I stream my video files (MP$ - 480p) I am receiving the following error- "Your connection to the server is not fast enough to stream this video. Check your Network".
I am receiving this error on ALL of my client devices (smart TV, Fire TV, etc). However, I am able to stream other services with NO issues on the same devices (NetFlix, Amazon, Video on demand).
I have made no recent changes to my wireless network.
I can also stream the same video files on my NAS with my smart TV using the built-in DNLA player with no issues.
Considering the facts above I would think this indicates a problem with the Plex server.
Any help or alternative viewpoints would be appreciated. Thank you.
