Unable to handle bad response

[fliker09]

This is what I get when trying with curl:

$ curl 'http://localhost:3010/api/v1/rss/peachastro'
{"detail":"Failed to fetch from https://xcancel.com/peachastro/rss"}
$ curl 'http://localhost:3010/api/v1/rss/peachastro'
{"detail":"Failed to fetch from https://nitter.poast.org/peachastro/rss"}
$ curl 'http://localhost:3010/api/v1/rss/peachastro'
Internal Server Error

Also got this when tried with RSS-to-Telegram-Bot on the same host:

ERROR: HTTP status code error (302 Found)
ERROR: HTTP status code error (500 Internal Server Error)
ERROR: HTTP status code error (403 Forbidden)

I am guessing the proxy is not auto-retrying a different instance when getting 302/403/500? Would be nice if it did!
