Nextcloud version (eg, 20.0.5) : latest
Operating system and version (eg, Ubuntu 20.04) : Ubuntu 22.04 LTS

The issue you are facing:
Loading any page on my nextcloud takes ages I’ve looked in the network tab and seen that https://cloud.woodburn.au/dist/core-common.js?v=25318951-9 takes minutes to load.
My setup is the docker AIO running behind an nginx reverse proxy using the below config

map $http_upgrade $connection_upgrade {
    default upgrade;
    '' close;
server {
listen 80;
listen [::]:80;
server_name cloud.woodburn.au;
if ($scheme = "http") {
        return 301 https://$host$request_uri;
location /.well-known/carddav {
    return 301 $scheme://$host/remote.php/dav;
location /.well-known/caldav {
    return 301 $scheme://$host/remote.php/dav;
location / {
        proxy_pass http://127.0.0.1:11000$request_uri;

I am using OpenID with authelia. And
Is this the first time you’ve seen this error? (Y/N):
