Need help with Google Search Console

Hey there,

I need some help on a problem I just found on Google Search Console...

So when I started my website I used Google Seach Console to index my site, which worked perfectly.

But I just looked into it and saw that it isn't indexed anymore.

There is also another page on the referring page tab which isn't mine (some casino site).

And if I try re-indexing it, it doesn't work.


I don't know what to do since I'm pretty new to Google Search Console-

Thanks in advance!
