ORA-12514: TNS:listener does not currently know of service requested in connect descriptor

Strange thing, but

I am getting this error when ora-12514 when trying to login to a database from another machine. This error does not appear when I log in as SYS user (as sysdba) and I am then successfully connected to CDB/PDB database. SYSTEM or any other users gives me ora-12514. I am using easy connect method.

When I am trying to do the same from where the database is installed, I can connect all the time for any user I was failing before.

I am using Windows 2019 and sqlplus. This is 19c installation on Windows 2019. It was working fine a week ago. Something has changed on customer site?
