Hey all, I’m very new to self-hosting and have no background in anything computer-related. I’ll explain in as much detail as I can. I’m running Plex on a Synology DS220+. I’m using the Plex app, i.e. not using Docker (see note below).
The issue: I can watch Plex on my local network in 4K, but outside my local network it barely makes it to 720p. I thought it was an issue with my upload speed, but I got gigabit last week and it hasn’t fixed the issue. I have remote access enabled in Plex through a manually-specified port. The issue persists with my own account and any friends who have access to my library.
I appreciate any advice, links or questions you can offer!
NOTE: I understand the benefits of Docker and I promise to transition in the future. I spent many hours learning and troubleshooting, and it was even functional at times, but eventually I needed something that just worked.
EDIT: You all have been so helpful and supportive. Thanks for meeting me where I’m at and sharing some potential issues.
You said you recently got a gigabit plan, but that’s related to your home download speed. Check to see what your upload speed actually is. Depending on your ISP’s plans, you might have a speedy download but a slow upload.
I tested between 800-900Mbps UP, closer to a full gig down.
If you go to canyouseeme.org and test your Plex port does it show as open?
Your new ISP might have CG-NAT meaning you don’t get your own IPv4 address and can’t be connected to directly.
Also stream a movie from your phone while connected to cellular data and then check that stream on the Plex admin screen to see what it says. IIRC the Plex Relay is fixed at 1mbps
These are excellent ideas to test where the bottleneck is. Thank you very much.
