pxp-agent config URI change in initial config vs first puppet run

[bastelfreak]

Describe the Bug

On a fresh PE 2021.7.7 I see the following diff on the first puppet run:

...

Why has the original config file https://pe.server.local:8140 but Puppet updates it to pe.server.local:8140? Why isn't it written correctly on the first place?

Expected Behavior

A config file that doesn't change on the first puppet run

Steps to Reproduce

curl --remote-header-name --location --remote-name 'https://pm.puppet.com/cgi-bin/download.cgi?dist=el&rel=8&arch=x86_64&ver=2021.7.7'
