the problem is with ASSP.
They use the SSL_version parameter of IO::Socket::SSL in a way which was never documented.
It only worked because it ignored wrong values until version 1.70, but with 1.70 additional
functionality was added to SSL_version so that it now needs to check the syntax and
rejects bad values.
You might fix the issue for you if you delete any references to SSL_version from assp/assp.pl
