Cannot login to Zoho Desk

Hi there,

I'm having issues logging into Zoho Desk. I go to my custom domain https://support.mydomain.com.au/support/xxxxx and enter my email address and password. I then get redirected to https://support.mydomain.manageengine.com/oauthorize which fails with "page not found" error.

I mainly use the mobile app and haven't logged into Zoho Desk by desktop for a week. Has something changed?

Thanks in advance,

James
