Unable to install on new Fairphone 4 via Easy/web installers, and security patch dates do not match on latest builds

/e/OS Devices Fairphone
6

I searched in installer code. This is the line which fails:

curl -o $MURENA_ROM_INFO https://images.ecloud.global/stable/FP4/e-latest-FP4.zip.prop

from file flash-scripts/linux/store-rom-info.sh · master · e / devices / Easy Installer · GitLab
This line tries do download the file, but fails.

But opening in the browser this link does work fine https://images.ecloud.global/stable/FP4/e-latest-FP4.zip.prop

This is similar issue, there problem was solved with manual install instead of using easy-installer:
