Intermittent SSL errors - SSL_do_handshake() failed (SSL: error:1408C095:SSL routines:SSL3_GET_FINISHED:digest check failed) while SSL handshaking to upstream Reverse proxy mode.. HELP

[David Taveras]

I must clarify the error in the logs is a 502 Bad Gateway.

I just tried to change the certificate entirely new.. with one I know
has been proven to work for months in the upstream box and I still get
the handsake error in the nginx box.

The problem seems to be more evident when there is multiple objects
being fetched at the same time ... If I make a single request and
reload it a lot it doesnt happen.

Again.. other clients with Mozilla do not get errors :( Iam about to
brake my head..
