Subject: pwqgen not functioning as expected

I would like to use pwqgen to generate a 10 character password that has at
least one upper case letter, at least one lower case letter, at least one
digit, and at least one special character.

I am running pwqgen using the following:

./pwqgen config=../../etc/passwdqc.conf

passwdqc.conf is as follows

It is believed these settings should create a 10 character password
(min/max =10) that must contain all 4 character classes, and no substring
of <= 3 can match a dictionary word.

Unfortunately, with these settings the following error is returned.

pwqgen: Failed to generate a passphrase.
This could happen for a number of reasons: you could have requested
an impossible passphrase length, or the access to kernel random number
pool could have failed.

If max is raised to 20 then a password such as, Canopy2Beware3swap, is
generated.  Of course this password does not even contain all character
classes (no special character).

Is there a way to use pwqgen in such a way that a 10-character password
can be generated using the criteria stated earlier?

Thank You.
