This looks like a timeout issue after ~60 seconds as opposed to a size issue. This happened before with the load balancer which we fixed and I verified. According to what I can see that LB setting is still set ok at 86400s. @jbuck any ideas? It seems weird that something else would be timing out. Production is using almost the same setup aside from the websocket without issue.

This issue is also reproducible with the Send Android build. However, the upload does not always hang after approx. 65 seconds like on the website, it stops after a period of time between approx. 30 and 180 seconds.

#1134 is a patch in-progress that might help solve GCS timeout issues and https://github.com/mozilla-services/cloudops-infra/pull/544 fixes the websocket timeout issue. Both need to be fixed to resolve this issue

This should be fixed on the dev site as of cd8ab54

I have verified this issue and is no longer reproducible on the https://send2.dev.lcip.org/ website.
