Nitter is fixed, you have to change the default instance.
Currently nitter.net throws a 403, they suggest to switch while they will enable back RSS feeds on their instance.
How can the default instance be changed?
Found it, went ahead and set "nitter.nl" as the default Twitter frontend domain, still not possible to create a list with public nitter timelines
I am using version 3.23.1
All instances (currently 6) with the update status 20.08.2023 or newer are working again.
3 has rss feed
