"Events not enabled." when accessing Statistics

Hello everyone,
I am experiencing a bug in Seatable 1.6.0.

When I open admin settings and then click on “Statistic” I get a popup saying “Events not enabled.” and the screen keeps loading.

The browser console has the following issue:

domain.com/api/v2.1/admin/statistics/active-users/?start=2021-01-10 00:00:00&end=2021-01-16 00:00:00 returns an error 400.

dtable_web.log has the following:

2021-01-16 16:11:01,885 [ERROR] seahub.api2.endpoints.admin.statistics:136 get Invalid URL ‘/admin/statistics/scripts-running/by-user/’: No schema supplied. Perhaps you meant http:///admin/statistics/scripts-running/by-user/?

Is this a known bug or is it just me?

Thank you

nginx reverse proxy config:

    server_name domain.com;

    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_redirect off;
    proxy_set_header Host $http_host;

location / {
    proxy_pass         http://127.0.0.1:8080;
    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;

}

This is likely to be a bug. We will check it.

I would like to note that I saw this on 1.5 too.
