Since last weekend (Jan. 26, 2019 or so), Netflix is unusable on my Roku 3 (4200). When I start watching something, it plays for a bit then stops to re-buffer (showing percentages) and then after a bit displays error "tvq-pm-100 (3.1.18)" with message "We're having trouble playing this title right now." I cannot figure out how to fix it.
Roku 3 (4200) showing OS is 9.0.0 build 4114-04
Connected via Ethernet cable directly to router.
I have tried all the troubleshooting I can think of. Restarted my home router (Verizon FIOS), restart Roku, uninstall Netflix app and reinstall app. At this point I have done a full factory reset of the Roku twice and started from scratch. No difference. I see no problems logged in my router's firewall log.
Streaming Netflix on my computer has no problem. Installed the Netflix app on my Playstation 4 (on the same network) and watched all night with no problem. Other apps on the Roku like Amazon Prime work with no issues. Seems like the issue is only the Netflix app on the Roku 3.
Everything has been working perfectly until a week ago (about January 26, 2019). Does that match the date of the push out of Roku OS 9? I was not monitoring what OS I was running and when updates happened so I have no idea if the OS updated right before this problem started. That's the only theory I have as to why this suddenly started happening.
