Schedule refresh error : Personal cloud connection : Big query

I have power bi scheduled reports connected with Personal cloud connector to bigquery, it was working perfectly fine, as of a sudden all scheduled refresh failed and this error . For 3 users out of 4. I can't find the problem , the reports refresh in power bi desktop perfectly fine. I made sure that the cloud service (big query) is not down for any reason, it is up and running and working normally. Where else could the problem be in ?
