Proposed Fix

Here is a possible fix, but we have to wait until Alpine is on NGINX 1.26

Current configuration

server {
    listen 8443 http2 ssl default_server;
    listen [::]:8443 http2 ssl default_server;
    # other configurations
}

Updated Configuration

server {
    listen 8443 ssl default_server;
    listen [::]:8443 ssl default_server;
    http2 on;
    # other configurations
}
