After upgrade on 20.4 I have problem with connection in Worksheet (using CONNECT)
I can connect using NETWORK alias in connect tree

But when I try connect in worksheet using same NETWORK alias I got error

Show TNS display NETWORK alias which I want to use

This is not exception for that NETWORK alias but to all (there is more than 300 aliases)
Connection in tree are working but not in worksheet.
On command prompt using sqlplus I can connect to all NETWORK alias
