Connector with GoogleDocs: Exception: a server error occurred. Please wait a bit and try

My team uses the Zotero connector with GoogleDocs.
We were very happy with it, but we suddenly can't use it anymore, due to connection problems to the server. The error message is slightly odd.

The report ID I submitted is 1178886283

Is this a general server/plugin problem that may affect a lot of people?
