Hi, I am receiving this error only while trying to connect to a database via TOAD.
Can connect via SQL*Plus and SQL Developer.
The recent change was the DB got upgraded from 12.1.1 to 12.1.2. Since then I am unable to connect over VPN. Was able to connect over the VPN prior to upgrade. Yet to try over LAN.
Using TOAD for Oracle 126.96.36.199
