RSS gives duplicate feeds - http ones along with https
I'm a user of nitter.it
Version [2022.08.30-8edfda3](https://github.com/zedeus/nitter/commit/8edfda3)

and once a day or few days all rss entries (from today and from the month ago - all of them) change from https to http and thus give duplicate entries into the reader

I'm using RSS Guard 4.2.2 reader on win 10 and have tons of  feeds but this issue only happens with nitter ones
