What happened to reddit/r/Thunderbird/ community?

I’ve noticed there was no activity on reddit for 5 months:
https://www.reddit.com/r/Thunderbird/

What happened?

Hi Juraj,
Only approved users are allowed to post to the sub.

But why? It looks like the EOL for the whole service…

Maybe someone can answer, I cannot access Reddit com on my Mobila mobile browser, and I cannot access my Wmlink2step Dot Net wordpress website, either. I have to access these on Chrome. What do I need to fix, change? Thanks
