I just did a fresh setup to verify if there is a issue with the master branch, this is not the case.
That means that this is a hosting environment issue, so what we suggest is to contact your hosting provider.
You can of course also create a support ticket with your hosting credentials so that our support team can investigate this, in case your hosting provider can not provide a solution.
Keep in mind that this is a paid service and costs € 48 per hour.
