Deploy = 502 Bad Gateway

[Claudio Weiler]

I'm getting an error with the message: "Error code 502, Bad Gateway" when I try to deploy my project to Nexus OSS 3.0.2

This is an intermittent error:

- pom artifacts always are published;

- jar artifacts mostly fails, rarely they are published with success.

My Nexus install are behind apache with following setup:

<VirtualHost *:443>
    ServerName nexus.intra.net
    ProxyPreserveHost On
    ProxyRequests Off

    ProxyPass / http://127.0.0.1:8082/
    ProxyPassReverse / http://127.0.0.1:8082/
    RequestHeader set X-Forwarded-Proto "https"
   
    SSLEngine on
    [server certificate infos]

    # Following configs are here from many suggestions found on web
    ProxyTimeout 300
    SSLProxyEngine on
    SSLProxyVerify none
    SSLProxyCheckPeerCN off
    SSLProxyCheckPeerName off
    SSLProxyProtocol all -SSLv2
</VirtualHost>

Nexus log says nothing, but Apache log says this on each fail request:

[Thu Nov 03 15:38:30.294869 2016] [proxy:error] [pid 11040] (32)Broken pipe: [client 10.6.41.65:64035] AH01084: pass request body failed to 127.0.0.1:8082 (127.0.0.1)

[Thu Nov 03 15:38:30.294924 2016] [proxy_http:error] [pid 11040] [client 10.6.41.65:64035] AH01097: pass request body failed to 127.0.0.1:8082 (127.0.0.1) from 10.6.41.65 ()

Base on this messages its a problem with reverse proxy config, but I dig a lot on the web, and all suggestions found I run a test without success (suggestions on code snippet above).

Any clues????

Thanks!!!

Ok,basically my searchs points to a problem with SSL, so I do a testing setup with plain http but the problem persists with same apache error messages. Acknowledge: this is not a SSL problem.

Upgraded to 3.1.0 but problem persists and now we have no more "remember me"!!!

More infos: apache access log says this on success and fail sequencial attempts:

Hi Claudio,

Could you please log an issue on http://issues.sonatype.org/ and include a support.zip file along with logs from the time this happened?

As for the 'remember me', it was removed due to security concerns based on a number of recently exposed vulnerabilities. Sorry if this impacted you.

[Claudio Weiler]

Hi Kelly,

Filled https://issues.sonatype.org/browse/NEXUS-11522

About 'remember me' I missed info on release log, or failed to find it. For me this is a 'like it' feature not a 'have to', moving on... ;)

Thanks!!
