Same problem here. Can't access any of my characters =(

Same issue, can't view or edit any character across multiple devices. 

the cobalt token gets blocked because of missing CORS headers
maybe that's related?

Getting a CORS error:

Access to fetch at 'https://auth-service.dndbeyond.com/v1/cobalt-token' from origin 'https://www.dndbeyond.com' has been blocked by CORS policy: No 'Access-Control-Allow-Origin' header is present on the requested resource. If an opaque response serves your needs, set the request's mode to 'no-cors' to fetch the resource with CORS disabled.

Same here started a vew minutes ago. I can´t even open the character sheet.

kinda working again now, cobalt tokens are back in the logs as well

I can access all of D&D Beyond that I normally could and I am properly logged in but every time I try and use a character sheet it says that something has gone wrong with Authentication. This has locked me out of all my character sheets.

Working now on mobile, still not on laptop ( chrome )

I am having a problem opening my character sheets, I was able to access them earlier yet now i cant open them over different browsers or on my app. any help would be much appreciated! 

Running into the issue with the Encounter Builder as well, can't even see any of the dozens of encounters I have sitting in there.

Nevermind, it's working now.

All looks good on this side now, thanks Sillvva
