We have a google cloud app engine java instance and we are connecting to it from a web site via rest api. We have agents in South Africa and America. It seems that sometimes it has intermitent issues in America but then during these times the staff in America don’t have the same issue and vice versa. I managed to replicate the issue and it seems that a request will fail with a CORS error but then a few seconds later I will try again and the same api call will go through. Please see the error below. Anyone know what the issue could be?
