I have a follow up on this and I didn't want to create another
topic for it. The simple hello world app I build with vibe-d does
not seem to work on the second compile+execution. It throws a
failed to listen on port/address error on console. I think it is
the same error as in [1]. Although the commit in [2] hasn't
seemed to fixed it for me. I appreciate any pointers.

I was also thinking about writing a tutorial about deployment on
EC2 Ubuntu 20.04. Does anyone think that would be helpful?

Best,
Selim

This is a known issue,  you have to set VibeHighEventPriority version for eg if you are using dub with json format add:

"versions": ["VibeHighEventPriority"]
