How to connecto DBeaver with Db2 using SSL self-signed certificate?

On Db2 v11.5.7.0 Linux/x86 server I have configured SSL using self-signed certificate following official IBM documentation https://www.ibm.com/docs/en/db2/11.5?topic=transit-tls-configuration-db2 I have tested this connection on my Windows PC using CLI and connection works fine. I assume Db2 server is configured correctly to support SSL. Now I would like to establish the same with Java application like DBeaver. On my Windows where DBeaver 22.1.3 is installed I imported SSL certificate with: keytool -import -trustcacerts -alias myalias -file C:\Programs\DBeaver\db2_ssl_tls\server.arm -keystore C:\Programs\DBeaver\db2_ssl_tls\mynewdbclient.jks Then I configured DBeaver connection to Db2 using SSL. I did like described in: https://selcukc.medium.com/dbeaver-create-ssl-connection-to-db2-72bd0948b6d4 or https://www.ibm.com/docs/en/fci/6.5.1?topic=application-connecting-db2-over-ssl-port like this: When I click on Test Connection button I get error: [jcc][t4][4.31.10] A communication error occurred during operations on the connection's underlying socket, socket input stream, or socket output stream. Error location: Reply.fill() - socketInputStream.read (-1). Message: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target. ERRORCODE=-4499, SQLSTATE=08001 PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target unable to find valid certification path to requested target unable to find valid certification path to requested target I have searched a lot of documentation on web, but all it seams to point to import CA certificate. But I am using self-signed certificate that does not need CA. Questions: 1. Do I need to setup something else? 2. Does DBeaver support self-signed certificates?
