UnexpectedValueException·GET / - 无效主机

I published my laravel app via Laravel Forge to DigitalOcean, and am now getting slammed with the following:

UnexpectedValueException · GET /
Invalid Host "*.piuandme.info"

STAGE
staging

URL
http://*.piuandme.info/

Stacktrace summary

index.php:49 · [main]

It's coming from the following 3 hosts, all in China:

  • http://*.piuandme.info/
  • http://*.lleiiell.info/
  • http://*.weinisishuicheng.com/

Any idea what is causing this and how to prevent it? I have multiple other Laravel apps up and running on DigitalOcean published the same way on different droplets with no issues.

Update: This issue has resolved itself, and seemed to have been DNS related, as well as my server not configured to ignore requests that don't match my domain names.
