Wait a second, you told you were sending dump request from host B to host A.

Let's clarify -- the page server is on A, the criu service is on B, the process
you want to dump is on B too. And you send dump request form host B where to?

Can you also check the dump logs for the line

    "Connecting to server"

to see one you need to set up the 4th log level.

Yes, the p.haul project does this:
https://github.com/xemul/p.haul/

but in a slightly different manner.
