ORA-12570: Network Session: Unexpected packet read error

user3539296Jan 9 2018 — edited Jan 9 2018

I am using Visual Studio 2013 with ODAC 12c Release 4. When trying to connect using ODP .NET Managed Driver I get this error message: ORA-12570: Network Session: Unexpected packet read error

My Server sqlnet.ora configuration:
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES
.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)

SQLNET
.CRYPTO_CHECKSUM_CLIENT=ACCEPTED
SQLNET
.CRYPTO_CHECKSUM_SERVER=ACCEPTED

I read a lot of similar errors online (Eg. Link). Is this error related to Network Data Encryption?

Thank you!
