My Bible has a little footnote that points to Proverbs 3:11-12 as the original source for Hebrews 12:6. Can you see what is different?
"My son, do not despise the Lord’s discipline, and do not resent His rebuke, because the Lord disciplines those He loves, as a father the son he delights in."
"My son, do not despise the Lord’s discipline, and do not resent His rebuke, because the Lord disciplines those He loves, as a father the son he delights in."
I see no conflict here only knit picking about how God guides His children through suffering to reveal His graciousness.
I'm not objecting to the language in either passage. Sometimes saints are called upon to suffer great adversity so perhaps scourging is not too strong a word.
