Can't connect to Hedgedoc

Hi,
I was using HedgeDoc to write specifications documents, and I recently noticed that the site is down. I don’t understand why I no longer have access to my documents. Previously, I used to log in with an email, but now it seems I have to log in with Git?
I’m a bit lost and confused — do you have a solution?
Here’s a link I used to access: https://pad.nixnet.services/

Edit by moderation: Removed link to specific note because of sensitive data

Hi @artyfw and welcome to the HedgeDoc community!

Unfortunately, we can’t tell what went wrong with the HedgeDoc instance over at pad.nixnet.serivces. Only the administrators of that instance can give details about that.
Currently, your link seems to work for me. In case of problems you might want to contact the nixnet.services administrators or check their support channels.
