I don’t know if you just rearranged something, but it works now. I previously wanted to subscribe to !mildlyinfuriating@lemmy.world from my instance, but it didn’t show up in the search. No idea what was going on there.

I can’t access your instance from my instance (feddit.de), although my instance is linked to yours. Does anyone have an idea what this could be?

I think the only solution that is not reliant on browser extension is some kind of URL Translator that is build into Lemmy.
