Packagist proxy broken for symfony/clock

[xvilo]

It seems I can't install symfony/clock component through the packagist repo on the hosted repman instance. I'm having the following behaviour:

$ composer require symfony/clock

In JsonFile.php line 347:

Getting that URL through CURL myself ends up in an empty response:
