Connection error in Jupyterpy at quantum mobile 23.04.03

[Guoyu YANG]

Dear Aiida users,

I am facing a problem with rabbitmq connection. 

I am using quantum mobile 23.04.03 on VirtualBox 7.0. 

If I use Jupyter Notebook following the guidance on this webpage

https://aiida.readthedocs.io/projects/aiida-core/en/latest/intro/installation.html#intro-install-jupyter, it cannot connect to rabbitmq.

The error message is shown on chrome: 

✘ rabbitmq:    Unable to connect to rabbitmq with URL: amqp://guest:gu...@127.0.0.1:5672?heartbeat=600
Error: ConnectionError: [Errno 111] Connect call failed ('127.0.0.1', 5672)

And on terminal, it shows:

$ verdi status
 ✔ version:     AiiDA v2.2.2
 ✔ config:      /home/max/.aiida
 ✔ profile:     generic
 ✔ storage:     Storage for 'generic' [open] @ postgresql://aiida:***@localhost:5432/aiidadb / DiskObjectStoreRepository: f5010831c906446994521daf1eac7c2e | /home/max/.aiida/repository/generic/container

I tried to follow the discussion before(https://groups.google.com/g/aiidausers/c/JAp4iSm7GNU/m/FCU7_Y48AgAJ)

$ conda activate aiida
(aiida) max@qmobile:~$ pip list | grep tornado
tornado                       6.2
(aiida) max@qmobile:~$ pip freeze | grep -E 'tornado|kiwipy|plumpy|pika'
aio-pika @ file:///home/conda/feedstock_root/build_artifacts/aio-pika_1642726664289/work
kiwipy @ file:///home/conda/feedstock_root/build_artifacts/kiwipy_1669740571191/work
plumpy @ file:///home/conda/feedstock_root/build_artifacts/plumpy_1680556968568/work
tornado @ file:///home/conda/feedstock_root/build_artifacts/tornado_1666788587690/work

There seems no problem. And I suppose the software versions should be OK in Quantum Mobile. 

But before testing the Jupyterpy, I passed the test on verdi status  after  adding the 

consumer_timeout = 36000000000

to   /etc/rabbitmq/rabbitmq-env.conf  

(https://aiida.readthedocs.io/projects/aiida-core/en/latest/intro/troubleshooting.html)

I am confused about rabbitmq. 

I would really appreciate any help!
