Hello Uriel,

do you see any error related to the parser in the log files, perhaps the Proxy-Authorization header somehow uses not the correct syntax? I'm not aware of any error that looses auth headers. You also not get a "stale nonce" result, which could be because of some bug in the nonce check code, which is the youngest part of the module.

Best regards,

Henning
