Microsoft NCSI on Nextcloud installed in Ubuntu server 18.04?

Hi guys, I’m very worry about something, I have Logwatch in ubuntu server 18.04 to send email notifications once a day, for my surprise I discover the following information.

/script: 1 Time(s)
/sdk: 1 Time(s)
/sqlite/main.php: 1 Time(s)
/sqlitemanager/main.php: 1 Time(s)
/test/sqlite/SQLiteManager-1.2.0/SQLiteMan … -1.2.0/main.php: 1 Time(s)
http://www.msftncsi.com/ncsi.txt: 1 Time(s)
408 Request Timeout
null: 1 Time(s)

Why a Microsoft utility is trying to run on a Linux server?, it doesn’t have a sense for me, when I open the link it shows me the following: ( Microsoft NCSI ), any help is very welcome and thanks in advance.

Is this a general linux question or is there a direct link to Nextcloud?
