My reader runs on a cheap VPS. Most feeds work fine there. But a few keep giving me 403. Reddit .rss, Tumblr, and sometimes YouTube. Same urls opens fine from my laptop at home, so it is the datacenter IP getting blocked, not the feed.
What helps me: - set a real User-Agent, not the default from the http library - slow the polling, one time per 30 min instead of every 5 - route only these domains through a residental proxy
For reddit the format is reddit.com/r/rss/.rss or reddit.com/user/name/.rss. Youtube is youtube.com/feeds/videos.xml?channel_id=ID.
I keep a small allowlist for proxy, rest stay direct. Tumblr still flaky even with this. If someone found better way i want to hear.
