Tiller Add-in Won't Load - Invalid Security Certificate

I went to load the add-in in Excel and I am getting the error:

“The content is blocked because it isn’t signed by a valid security certificate.”

Are others getting this error as well?

@heather

I am getting the same error.

I am getting this as well. I can’t find much else about it in the help forums, it might be a new issue today.

Either they pushed a new version through without the proper certificate or the certificate expired.

Mine is working now.

Same here. Team Tiller to the rescue.

@dminches, glad to hear this is resolved. The support team escalated internally and we were able to push a fix on Saturday!
