NTLM auth causes Secure Connection Failed

I have a site trying to do NTLM auth from an F5 APM device. On Firefox version 50.1 this all works ok, but for users on version 45 they intermittently get the error:

Secure Connection Failed The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.

Thoughts on the cause/fix of this issue? Others browsers are fine.

Thanks

I assume you meant 54 instead of 45, correct?

This could involve a known issue with regard to http 2 connections and Firefox failing to fall back to http 1 due to NTLM being incompatible with it. That issue should have been fixed in 53, but some reported it to have returned in 53.0.3 and 54. It should however be fixed in 55, scheduled for release one week from now.

If so, you can temporary work around the issue by either disabling HTTP/2 on the server, or by toggling the network.http.spdy.enabled.http2 preference to false in about:config. See the following article and bugs for more info:
