Here is mine https://gist.github.com/jeena/6179470a8d616455f30635a5c71f5f64 which had a similar problem with the comments, although I couldn't post comments on my own instance either.

For me the thing was that I had to add:

map $http_upgrade $connection_upgrade { default upgrade; '' close; }

and

proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade;

And also change the nginx in the docker to port 8080 so my normal nginx could keep running on 80 and handle all the ssl certificate stuff.

My setup is:

Browser -> native Nginx -> docker Nginx -> lemmy

How would one instance know that I set up a new instance without a central service?

They've been loosing money for 20 years, now they want the IPO so they need to show that they can also make money.

There is a workaround to groups: https://fedi.tips/how-to-use-groups-on-the-fediverse/

That's what consulates and embassies are for, no need to have hidden Chinese police in the back of the restaurant.

Ah this is the real tip, thanks!

We have @foosel perhaps she should start the 3d printing one here :D

Oh, and even if they're annoying, I understand how federation works and that users from lemmygrad could comment there etc. and I can handle the shills, what I was surprised about were the mods on lemmy.ml which started deleting my comments. Doing this, they make it impossible for me to even try to engage in a discussion and show a different point of view to the tankies.

As far as I understood, those were people who had accounts on lemmy.ml, not lemmygrad.ml
