+1 for Lemmy.ca. I was in Lemmy.ml first, but it was incredibly laggy and unresponsive so I moved here two months ago during the Reddit exodus and have stayed since. Lemmy.ca is always super responsive for me. Living near the server where Lemmy.ca is based probably helps as well.
Does everything else work normally (like YouTube, etc.)? If they’re not working correctly, try unplugging your wifi router and repluging after a minute. Otherwise, I don’t know.
I see a couple communities from beehaw doing a quick search. (askbeehaw and support)
The results seem strangely limited though. You may have to check for specific communities yourself though. (I stay away from drama sources for any social media usually.)
