This is most likely bug 5055 fixed in August 2021:
https://bugs.squid-cache.org/show_bug.cgi?id=5055

In many environments, Squid v5 is unusable without that bug fix. I do
not know whether the v5 maintainer plans to officially backport the fix
from master/v6 to v5, but we would be happy to assist with that. FWIW,
Factory has an _unofficial_ backport to v5-based code at:

HTH,
