-----------------------------------------------
Could you please send me the wirelog of the session? HttpClient 5 uses log4j2.
Here is the logging config

> Digest auth: Nonce counter not incremented after reuse
> ------------------------------------------------------
>
> Key: HTTPCLIENT-1855
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1855
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient (classic)
> Affects Versions: 4.5.2
> Reporter: Alessandro Gherardi
> Assignee: Oleg Kalnichevski
> Fix For: 4.5.4, 4.6 Alpha1
>
> Attachments: HttpClient5Digest.java, HttpClientDigest.java,
> wireshark.txt
>
>
> I have a client app using httpclient 4.5.2 with BasicCredentialsProvider and
> BasicAuthCache. and web server that requires HTTP digest authentication.
> The client sends 3 requests to the web server.
> When the app sends the first request, the server returns an HTTP 401 with a
> digest challenge. httpclient automatically retries the request with the
> Authorization header. The header contains the nonce returned by the server
> and a nonce counter (nc) of 1. The retry succeeds and httpclient caches the
> DigestScheme.
> For the second request, httpclient uses the cached DigestScheme to calculate
> the Authorization header pre-emptively. The header contains the same nonce
> and specifies a nonce counter of 2. The request succeed without requiring a
> retry.
> For the third request, httpclient uses the cached DigestScheme to calculate
> the Authorization header pre-emptively. Even though the header contains the
> same nonce, the nonce counter is set to 2 again. This causes the server to
> return a 401. httpclient should have incremented the nonce counter to 3.
> I believe that the root cause of this problem is that, although DigestScheme
> increases the nonceCount field every time the authenticate() method is
> called, HttpAuthenticator does not re-cache DigestScheme after reusing it.
> The re-cache is needed because BasicAuthCache stores DigestScheme in
> serialized format.
