Developer tools tend to have a bevy of drivers, so  they  can connect to databases regardless of version.  Then, of  course, they won't tell  you the driver they used.

I'd say, upgrade your Oracle client, but that  can  be.... troublesome.   If you  install a new version, it will take the place of the older one.   Could spell trouble if you have an old version of Oracle.   (we recently decommissioned a 9i database; I was so happy to kick  11g drivers to the curb.)

If you load a newer  Oracle OCI and things  go belly, well, there are articles about how to uninstall, remove files, remove items from the Registry, etc.
https://docs.oracle.com/cd/B16255_01/doc/install.102/b14312/deinstall.htm

If you need both an  older and a newer version., you need to remove the older one, install the new one, then reinstall the older one.  That's way the y will play niver.

Good luck and I seriously mean it.

I looked at the sql.net file and i see the same settings for server and client (encryption type) - there was an upgrade to the oracle database based on the application

but the thing is i can connect with no issues from SQL developer tool

If I were you, I'd ask your DBA group  if they modified the database or upgraded Oracle.    Assuming no changes happened in your Alteryx environment.
