Hi guys, hope someone can help me with my current problem. I have two virtual machines. One is running the Prefect server and I try to deploy a flow from the other one. I have started the Prefect server successfully

ubuntu in 🌐 instance-20230102-1221 in ~ via 🅒 prefect took 5m57s 
❯ prefect config set PREFECT_SERVER_API_HOST=0.0.0.0
Set 'PREFECT_SERVER_API_HOST' to '0.0.0.0'.
Updated profile 'default'.

ubuntu in 🌐 instance-20230102-1221 in ~ via 🅒 prefect took 3s 
❯ prefect server  start

Configure Prefect to communicate with the server with:

    prefect config set PREFECT_API_URL=<http://0.0.0.0:4200/api>

View the API reference documentation at <http://0.0.0.0:4200/docs>

Check out the dashboard at <http://0.0.0.0:4200>

I am able to connect to the Prefect UI in the browser, by replacing

0.0.0.0

with the ip address of the vm. On my second vm, i have done the following:

ubuntu in 🌐 instance-20221129-2229 in yfin-db/yfin_db on  main [!?] via 🐍 v3.11.0 via 🅒 main took 6m37s 
❯ prefect config set PREFECT_API_URL=<http://xxx.yyy.zzz.xxx:4200/api>
Set 'PREFECT_API_URL' to '<http://xxx.yyy.zzz.xxx:4200/api>'.
Updated profile 'default'.

ubuntu in 🌐 instance-20221129-2229 in yfin-db/yfin_db on  main [!?] via 🐍 v3.11.0 via 🅒 main took 6s 
❯ prefect deployment apply healthcheck-deployment.yaml 
Successfully loaded 'healthcheck'
Deployment 'healthcheck/healthcheck' successfully created with id '52b59be9-fe11-49d1-acad-3257f3fc758d'.
View Deployment in UI: <http://xxx.yyy.zzz.xxx:4200/deployments/deployment/52b59be9-fe11-49d1-acad-3257f3fc758d>

To execute flow runs from this deployment, start an agent that pulls work from the 'test' work queue:
$ prefect agent start -q 'test'

As you can see, I have changed the

PREFECT_API_URL

to the Prefect server running on my first vm. Than I have applied the deployment and Prefect tells me, that the deployment was successfully created. However, the deployment does not appear in the Prefect UI. Did I miss anything?

What is the network configuration for the two vms? This looks like a virtual network misconfiguration.

This is how the ingress rules for my vnc looks like Which ports needs to be opend?

export PREFECT_SERVER_API_HOST="127.0.0.1"
prefect server start --host 0.0.0.0

Maybe try this?

Ok. Thanks. I´ll give it a try.

Awesome!
