Submission server is down before extended challenge deadline

Is anyone else experiencing issues in submitting to this track? The organizers sent out the following information 10 days ago

The LID Challenge has been postponed to Jun 9, 2019 7:59:59 AM CST.

Accordingly, there should be ~1.5h left for submission but the system won’t accept them.

Hi @pkontschieder,
I think this is resolved now. Sorry for the inconvenience caused.
