Connection reset by peer on new install


We have a fresh install and it seems to be accessible, but there is the following error in the Nginx logs, which prevents checkers like SSL Labs accessing the site:

(104: Connection reset by peer) while proxying and reading from upstream, client:, server:, upstream: "", bytes from/to client:0/7, bytes from/to upstream:7/126

I did some browsing around and adjusted the 60-jitsi-meet.confto look like this:
map $ssl_preread_alpn_protocols $upstream {
~\bh2\b web;
~\bh2c\b web;
~\bhttp/1.1\b web;
~\bh2,http/1.1\b web;
~\bh2c,http/1.1\b web;
default turn;
as explained in another threat but no luck. Maybe someone else has an idea as to what might cause this?

I am seeing the same on a new install.

Any ideas?
