Connection refused when attempting to contact 127.0.0.1:8080

Hello,
I have problem with this new oracle server
Operating system: Windows XP SP 2
Oracle version: Oracle Database 10g Express Edition Beta Release for Microsoft Windows

I finish the installation and I start the server:
D:\oraclexe\app\oracle\product\10.2.0\server\BIN>net start OracleMTSRecoveryServ
ice
The OracleMTSRecoveryService service is starting.
The OracleMTSRecoveryService service was started successfully.
D:\oraclexe\app\oracle\product\10.2.0\server\BIN>net start OracleXETNSListener
The OracleXETNSListener service is starting.
The OracleXETNSListener service was started successfully.
D:\oraclexe\app\oracle\product\10.2.0\server\BIN>net start OracleServiceXE
The OracleServiceXE service is starting.
The OracleServiceXE service was started successfully.

And if I try to connect with admin panel (http://127.0.0.1:8080/htmldb) via browser, I get "connection refused when attempting to contact 127.0.0.1:8080".
I disabled firewall and same thing.
I installed oracle into another computer and nothing new.
My friend tried it on his windows XP and the same thing :(

What platform are you on? What are the permissions for the keyfile and directory containing the keyfile? In particular, are the file/directory permission set to permit only the current user to read them? Our new library defaults to enforcing the recommended SSH security practice of having keyfiles be readable by only the current user.

Hi John,

i'm running SQL Developer on MacOS 10.15.2. The file permission for the private key is limited to "rw-------" (600). But the directory (".ssh") containing the keys has a lower permission level with "rwxr-xr-x". I limited it to "rwx------" and now the SSH Connections in SQL Developer are working again! Great support, thank you!

I'm glad that you were able to solve your issue. The lack of proper feedback with our new SSH library is something I am looking into. In a future release I hope to provide detailed information when we run into a configuration issue.

I had the same problem in my environment.
(SQLDeveloper version 21.2.1.204, build 204.1703)

After investigating the cause, I found that it was a bug in Apache Mina SSHD 2.6.0.
https://issues.apache.org/jira/browse/SSHD-1105
(I've confirmed that this fix solves the problem)

This bug has been fixed in sshd-2.7.0.

I want you to update the version of sshd included in SQLDeveloper.

Thanks for the update. Can you test in your environment with our 21.4.3 release? We updated to sshd-2.7.0 in that release, so hopefully it works out of the box.

Thank you for your comment.
After upgrading, it worked fine!
(SQL Developer version 21.4.3.063, build 063.0100)

The Japanese page is still 21.2.1, so I'd be happy if you could update it.
