Oracle Cloud Free Tier - Autonomous DB - Cannot connect
SummaryATP - Neither APEX Link, nor SQL Dev Web Link, nor connect using local SQL Dev 19.2 works
I just wanted to give Oracle Cloud a test drive using the newly announced Always Free tier. But sadly, after provisioning ATP DB instance (serverless), I found that I cannot use it at all.
In the service console (Development), neither of the APEX link nor the SQL Developer Web links work. Both give the below error message (see image)
Furthermore, when I try to connect with a locally installed SQL Developer 19.2 using the connect option "Cloud Wallet" and specifying the download wallet.zip, SQL Developer displays the error message (in german): "Status: Nicht erfolgreich - Test nicht erfolgreich: I/O Fehler: Remote host closed connection during handshake".
