I think you need to turn the gamerules "sendcommandfeedback" and "commandblockoutput" to false in order for it to not spam the chat. If the problem persists it is probably a bug in the server software.
Clark is right. The problem you have is just that you are using 19032 instead of 19132. As clark said, all you have to do is change the port in the server.properties file.
