I encountered a problem when connecting to a NAS shared directory using spring-integration-smb. The problem is that I was able to connect to another shared Nas directory but for the pre-prod Nas, I encountered this problem. Also, the shared server administrator confirmed that both directories have the same configuration. You will find below the stack encountered

here is my code :

  @Bean
    public SmbSessionFactory smbSessionFactory() {
        VaultResponse vaultResponse = vaultTemplate
                .opsForKeyValue(vaultPath, VaultKeyValueOperationsSupport.KeyValueBackend.KV_2).get(vaultSecretsPath.toLowerCase());
        SmbSessionFactory smbSession = new SmbSessionFactory();
        smbSession.setHost(properties.getNasHost());
        smbSession.setPort(properties.getNasPort());
        smbSession.setDomain(properties.getNasDomain());
        if (vaultResponse != null) {
            Map<String, Object> data = vaultResponse.getData();
            smbSession.setUsername(data != null && data.get("nasUsername") != null ? (String) data.get("nasUsername") : "");
            smbSession.setPassword(data != null && data.get("nasPassword") != null ? (String) data.get("nasPassword") : "");
        }
       smbSession.setShareAndDir(properties.getNasShareAndDir());
        smbSession.setReplaceFile(true);
        smbSession.setSmbMinVersion(DialectVersion.SMB1);
        smbSession.setSmbMaxVersion(DialectVersion.SMB311);
        return smbSession;
    }

thank you in advance,
