Issues running a Prefect flow on a corporate network (TCP_MISS/503)

[matganzala]

Bug summary

Hi everyone,
I built a Selenium-based scraping workflow and I'm orchestrating it using Prefect. Everything works fine when I'm outside the corporate network, but when I try to run the flow inside the corporate environment it fails.

While checking the Prefect server logs and the proxy backlog, I found this entry:

TCP_MISS/503 2368 GET http://10.14.202.234:4200/api/admin/version

My Prefect server is started with:

prefect server start --host 10.14.202.234 --port 4200

It looks like the corporate proxy/firewall might be blocking internal communication between the agent and the server.

Has anyone faced something similar?
Do I need additional configuration to run Prefect behind a corporate proxy? Any tips on how to properly expose / allow traffic to the API endpoints?

Thanks in advance!

Version info

Prefect version 3.6
