Hi,
I have a sample setup of Metabase in HA mode where two servers running Metabase and nginx have been configured behind a load balancer (HAProxy). The LB is set to use least connection.
My problem for now is that once in a while when loading Metabase, I will get a blank screen even though from the developer console, I have everything returning status 200.
When I clear cookies and cache, Im able to reload Metabase but when I log in, I get the "New login" email no matter how many times I login. As per my understanding, setting up HA Metabase was just a matter of creating two identical instances sharing the same DB and nothing else.
Could anyone with experience with this please share if theres more I need to do?

Below is a slice of my nginx config on both servers. Removed unnecessary details about the server and SSL
server {
listen [::]:443 ssl;
listen 443 ssl;
location / {
proxy_pass http://127.0.0.1:3000;
proxy_redirect off;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Host $server_name;
proxy_set_header X-Forwarded-Proto $scheme;

add_header X-Server-Hostname $hostname;
}
}
