It’s normal for me to use the browser to open the website through this agent,
But it’s not normal on ttrss,
Can you tell me where I haven’t set it

(Moved to unsupported)

Dunno, maybe check the IP address?

going by this error message either your proxy server rejects tt-rss or origin server does it when receiving proxied connection (cloudflare?), you might get more information in your proxy logs

there are no other proxy-related settings other than _HTTP_PROXY
