Comment 1 for bug 1653856

I've seen several related gate failure. What I have seen in the logs is "Unable to establish connection to XXXX: ('Connection aborted.', BadStatusLine("''",))" [1] It doesn"t only happen with token creation.

It feels (no proof) the errors started poping while we added HTTPS everywhere.
