Is there any chance there was sizeable clock skew between client and server? I would've expected the default ~16min expiration time to generally be enough, though -- the only other explanation I can think of would be a mismatch in HMAC algorithm. Without more logs or proxy-server configs, it's hard to offer much more guidance.
