Google Crawl causes Exception

[cbellgit]

Got an email this morning that there was an error on my site.

Running SQRL Login Version 1.1.2 and Wordpress 5.2.2.

Google Bot was trying to access https://[site redacted]/wp-admin/admin-post.php?action=sqrl_auth&nut=1lzpubCI7DwVNkTOKcdnBorSqJeY9yXL&can=aHR0cHM6Ly93d3cuaW5vbGxlYi5jb20

which threw the following error:
