Hi @GeorgeIoak I have asked one of the team to take a look at this. I see that you are using a provider that we haven't used. Have you attempted this locally within a virtual environment or linux system?

Hi @GeorgeIoak , I've tried to reproduce the error on my end but to no success. Note that I do not have a Digital Ocean Server so I had to reproduce this on my VM (i.e. Virtual Box). To setup volttron, I did a fresh install of volttron (python bootstrap.py --force), ran the RMQ dependencies script (./scripts/rabbit_dependencies.sh debian), activated the virtual environment (source env/bin/activate), configured the platform to use RMQ (python bootstrap.py --rabbitmq single), and then started volttron (volttron -vv). I did read the attached logs and saw that there were some RMQ connection errors. One follow up questions for you: Did you use python bootstrap.py --rabbitmq single to install RabbitMQ before starting volttron?

Hi @bonicim , thank for looking into this. Virtual Box was my first choice to try this out but unfortunately I run Windows 10 on my main desktop and my VMs are currently not working.

I had an old unused instance at Digital Ocean so I thought I'd try it but it did need some severe upgrading so something there could have gone wrong. Your steps look familiar except for adding single for RMQ.

I did notice the RMQ errors and wondered if they had anything to do with using localhost instead of a FQDN?

I'll go back and wipe out that install of volttron and try it again and report back if I get the same error or not.

i have the same problem, Is there a solution?

@GeorgeIoak we are generally now using DockerDesktop for our development environments. They seem to work well for us.
