We use sonatype nexus on Windows Server 2008 R2. To be able to access external repositories we use an corporate http proxy server. Therefore we entered in Nexus GUI->Server the values "proxy host", "proxy port", "username" and "password". After migration from Nexus 2.2 to 2.10.0-02 the nexus server is not able to access external repositories.
If now I go to Nexus GUI-> Repositories->Central->Browse Remote->Refresh the remote repository is not visible. The wrapper.log contains following log entries (original data was replaced by <proxyhost>:<proxyport> and <proxyuser>):

Wireshark capture looks like this:
43 1.803445000 <nexus> <proxyhost> HTTP 278 GET http://repo1.maven.org/maven2/?delimiter=/ HTTP/1.1
51 1.814045000 <nexus> <proxyhost> HTTP 278 GET http://repo1.maven.org/maven2/?delimiter=/ HTTP/1.1
55 1.819731000 <proxyhost> <nexus> HTTP 1014 HTTP/1.1 407 Proxy Authorization Required (text/html)
all GET requests doesn't have any authentication headers. Why Nexus does not repeat the GET request with credentials after HTTP 407?
Does anyone have similar issue?
It sounds like the proxy server might be configured to use NTLM authentication? Try entering the "NT LAN Manager Domain" in the proxy authentication also.
