server returns HTTP 416

[hellt]

Describe the bug

A check on external link such as https://goreleaser.com/ produced HTTP 416 error which is a result of Range: 0?

Any methods to solve this false positive?

To Reproduce

Create a link to https://goreleaser.com/ and run htmltest.

.htmltest.yml

DirectoryPath: ./public
IgnoreURLs:
  - fonts.gstatic.com
IgnoreDirectoryMissingTrailingSlash: true
IgnoreAltMissing: true
IgnoreSSLVerify: true
IgnoreDirs:
  - overrides
  - page
IgnoreInternalEmptyHash: true

Expected behaviour

While alternative solution (#162) to check external link is not yet implemented it would be nice to be able to ignore HTTP 416 specifically?
