Error while creating SMBJ Connection - java.util.concurrent.TimeoutException: Timeout expired

[hkmudgal29]

Hi,
I am using below Java code using smbj-0.13.0 library on apache tomcat 10.1.23 and java version "17.0.10" 2024-01-16 LTS on RHEL 9.3 (Plow) VM. I tried telnet on host and port 445 from VM and it's working fine even ping is working fine -
try (SMBClient smbClient = new SMBClient(config)) {
log.info("smbClient initialized - "+smbClient);
try (Connection connection = smbClient.connect(SMB_HOST)) {
log.info("Connection created: "+connection);
AuthenticationContext ac = new AuthenticationContext(smbUser, smbPassword.toCharArray(), null);
try (Session session = connection.authenticate(ac)) {
log.info("Session Created: "+session);
try (DiskShare share = (DiskShare) session.connectShare(SMB_SHARE)) {
ListObjectsV2Request listReq = ListObjectsV2Request.builder().bucket(BUCKET_NAME).prefix(date).build();
} catch (Exception e) {
log.error("Exception while making DiskShare : "+e.getMessage());
}
} catch (Exception e) {
log.error("Exception while making Session : "+e.getMessage());
}
} catch (Exception e) {
log.error("Exception while Connection for SMB HOST: {}, Error: {}", SMB_HOST, e.getMessage());
}
} catch (Exception e) {
log.error("Exception while initializing SMBClient(), error: " + e.getMessage());
}

It's failing on line - try (Connection connection = smbClient.connect(SMB_HOST)) with following error -

However it's working on my laptop macos using same apache tomcat server and java version "17.0.6" 2023-01-17 LTS.

Can you help me to fix the issue ?
