 H:   Looking for prefregex '^(?P<content>.+)$'
 T:   Pre-filter matched {'content': ' query-errors: info: client @0x7f01e00004e0 123.123.123.123#80 (sl): view red: query failed (REFUSED) for sl/IN/ANY at query.c:5445'}

 and note the value of `'content:'`. This content comes after the `datepattern`; we have successfully parse the date timestamp.  Next, remaining content is then fed into the `failregex` patterns.
 
 Note: Please note in 'content': value that there is an extra space at the beginning of that value so be careful with the ‘`^`‘ and make sure it starts with ‘`^ `‘ (note a space after caret symbol.)
