That's for responding @astitcher . I will try to open an issue if this is
indeed a problem. It might just be a config issue as I am new to this. Here is
my code
```
urls = ['activemq1`, `activemq2`]
conn = BlockingConnection(
urls=urls, user="admin", password="$pass", sasl_enabled=True,
allow_insecure_mechs=True, allowed_mechs="ANONYMOUS",
reconnect=Backoff(max_tries=5)
)
sender = conn.create_sender("test1")
creation_time = datetime.utcnow().timestamp()
message = Message(
body="hello workd",
creation_time=creation_time,
expiry_time=creation_time + 200,
durable=True,
)
sender.send(message)
```
I am running this code with docker-compose that has 2 activemq services
(activemq1 and activemq2). It works fine if the activemq1 service is running.
But when I kill activemq1 service to test fail over this code errors with this
message:
```
