Description
When using a dnode, create a connect like this: taos.connect(host=self.host, port=self.port, user=self.user, password=self.pwd, database=self.db, timezone=self.tz).When I use this connect object to query sql twice,it throws an exception:[0x000b]: Unable to establish connection
But, When I create a connect like this: taos.connect(user=self.user, password=self.pwd, database=self.db, timezone=self.tz), it's all ok.In addition, the passing host and port are displayed with multiple dnodes without error too.

Research direction
Reproduce the reported behavior with the Python taos.connect calls in the issue, using a dnode host and port and issuing two queries through the same connection. Compare it with the connection that omits host and port; done means the dnode connection can execute both queries without an Unable to establish connection exception.
