Yesterday we made some upgrades to some internal authentication modules. We rolled these changes out to all our servers.
Unfortunately due to an interaction with the old code branch running the old web interface, this caused a compatiability problem with the authentication process, causing all logins to unfortunately fail.
We’ve now fixed this, so logins to the old interface are working again.
If possible, we recommend people use the new web interface if possible. The old web interface is not getting updates any more, and all new features and updates are being done on the new web interface.
