Looks like they are exit scamming. They already transferred 200k DNA from their wallet to Qtrade to dump it. I have no strong proof but it looks very suspicious:
Qbtc is most likely dumping our coins on us. This is not a great contribution ... They are a cancer for us. Already dumped >200k DNA our coins on us.
Looks like I was right. Withdrawals on Qtrade are locked and we have announcment:

Dear all, Sorry for the all inconvenience. QBTC is cooperating with the police investigation. In the meantime, QBTC is not able to process withdrawal, we are very sorry for this and we will fix all problems ASAP. Thanks for your support!!
Good thing is that there are only 40k DNA left on their wallets. ~260k was already dumped. Whats interresting is that deposits still works, but are not recomended [facepalm]!

Why the withdrawal does not work, but does the input of funds work?

because deposit is automatical, and I dont recommend you to do that.
