Upgrade Issues

[URRLEON]

Description

I apply upgrades to access DB2 using SSL routinely.
After I installed the upgrade and opened DBeaver I received a message that a driver was missing. In by case the IBM DB2 driver. I downloaded the driver and now I get this error: when I try to open the DB: [jcc][t4][20162][14259][4.34.30] Connection failed: could not establish a SSL connection with the server. The connection has been configured to use hostname validation and the servers TLS certificate does not contain a hostname or IP address which matches the value configured by the client. ERRORCODE=-20576, SQLSTATE=08001

The DB2 server is managed by IBM so I have limited access.
Why did the driver disappear after the upgrade.
How do I fix the error reported. All the configuration data is the same and has not changed.

I uninstalled the new release 25.1.2 and installed Version 25.1.1.202506221557 but I'm still getting the same error.

DBeaver Version

Version 25.1.1.202506221557

Operating System

Windows 11

Database and driver

DB2 for LUW

Steps to reproduce

Try to connect to the database.

@URRLEON Thank you for your submission. Could you tell us what driver version you are using please? Can you send us a screen shot of the connection dialog page too? And can you also include the logfile please ? Please send the log files. You can find instructions here: https://dbeaver.com/docs/wiki/Log-files/. Thank you.

Hi Dave, I went ahead and reinstalled the latest version since the previous version now has the same issue. Where would I find the driver installed? Would I run the db2level command to get the version used by DBeaver? Where is the log? Do I run the 'Collect Diagnostic Info' and send the zip file?

I attached the run time log found in Window -> Show View -> Error Log. I still need directions on finding the DB2 version I'm using with DBeaver.

I have solved the problem adding a new driver property:
sslClientHostnameValidation=off

I am not sure why I this just started to happen when DBeaver was upgraded, but if someone can nail it down I will appreciate the explanation. Thanks!
