I'm trying to create a database connection in SnapDevelop 2019 R3 (I tried in R2 also) to an Oracle database, but I get the error "ORA-12537: Network Session: End of file". It's strange because I can connect to this database in Powerbuilder without any trouble. This database is in Oracle's cloud, and the service name is a bit long (38 characters).
I haven't found how to solve this issue so I'm stuck here and cannot continue the customer's project. Can anybody help me please?
