jenkins - Nexus returns error 502 (Bad Gateway) when publishing artifacts -


i've completed installation of sonatype nexus 3.2.1-01 , i'm trying publish artifacts using jenkins job , nexus artifact uploader 2.9 plugin.

the upload starts fine:

100 % completed (572 kb / 572 kb).

but throws the error:

return code is: 502, reasonphrase:bad gateway.

both jenkins , nexus servers run behind reverse proxy believe source of issue.

the apache log seems suggest request not replied nexus:

[thu apr 06 18:50:46.128569 2017] [proxy:error] [pid 10327] (32)broken pipe: 

[client some_ip:57928] ah01084: pass request body failed 0.0.0.0:8081 (0.0.0.0) [thu apr 06 18:50:46.128649 2017] [proxy_http:error] [pid 10327] [client some_ip:57928] ah01097: pass request body failed 0.0.0.0:8081 (0.0.0.0) some_ip ()

this virtualhost config in apache sonar server:

<ifmodule mod_ssl.c> <virtualhost *:443>      serveradmin some@email.com      servername  some.website.com      serveralias nsome.website.com       documentroot /srv/www/nexus/public_html/      errorlog /srv/www/nexus/logs/error.log      customlog /srv/www/nexus/logs/access.log combined       proxypreservehost on      proxypass / http://0.0.0.0:8081/      proxypassreverse / http://0.0.0.0:8081/      proxypassreverse / https://some.website.com/       sslcertificatefile /etc/letsencrypt/live/some.website.com/cert.pem      sslcertificatekeyfile /etc/letsencrypt/live/some.website.com/privkey.pem      include /etc/letsencrypt/options-ssl-apache.conf      sslcertificatechainfile /etc/letsencrypt/live/some.website.com/chain.pem </virtualhost> </ifmodule>

i've tried add following, explained in other answers, did not help:

1) disabling check on ssl certificates (although these valid):

sslproxyengine on sslproxyverify none sslproxycheckpeercn off sslproxycheckpeername off

2) forcing requests headers:

requestheader set x-forwarded-proto "https" requestheader set x-forwarded-port "443"

3) settting timeouts , keepalive options in proxypass line:

proxypass / http://0.0.0.0:8081/ retry=1 acquire=3000 timeout=600 keepalive=on

at end error 502 (bad gateway) had nothing root cause of problem. version listed on artifact published snapshot version did not comply nexus policy , triggering error.
