nginx is logging a deprecation notice for the current HTTP2 syntax:

2024/11/25 08:06:48 [warn] 80936#100292: the "listen ... http2" directive is deprecated, use the "http2" directive instead in /var/etc/nginx-webConfigurator.conf:30
2024/11/25 08:06:48 [warn] 80936#100292: the "listen ... http2" directive is deprecated, use the "http2" directive instead in /var/etc/nginx-webConfigurator.conf:31

The lines in question are:

                listen 443 ssl http2;
                listen [::]:443 ssl http2;

These should be changed to:

                listen 443 ssl;
                listen [::]:443 ssl;
                http2 on;

That should be done for both the GUI and captive portal web server configurations.
