    Set up a docker proxy repository against dockerhub, pull an image through it. Then disable outbound network access (for testing, I did this by setting an http proxy server that doesn't exist in the HTTP settings). Then try to pull the image again. This fails with a 502 error. {quote} docker pull 192.168.1.83:18887/tomcat Using default tag: latest Error response from daemon: Received unexpected HTTP status: 502 Bad Gateway {quote} The nexus.log shows what you would expect: {noformat} 2016-06-29 12:32:40,579-0500 INFO [qtp384210737-175] admin org.sonatype.nexus.internal.httpclient.HttpClientManagerImpl - Saving configuration: HttpClientConfiguration{connection=null, proxy=ProxyConfiguration{http=ProxyServerConfiguration{enabled=true, host='192.168.1.65', port=8889, authentication=null}, https=null, nonProxyHosts=null}, authentication=null} 2016-06-29 12:32:47,533-0500 WARN [qtp384210737-73] admin org.sonatype.nexus.repository.docker.internal.DockerProxyFacetImpl - Failed to fetch: v2/library/tomcat/manifests/latest org.apache.http.conn.HttpHostConnectException: Connect to 192.168.1.65:8889 [/192.168.1.65] failed: Connection refused at org.apache.http.impl.conn.DefaultHttpClientConnectionOperator.connect(DefaultHttpClientConnectionOperator.java:151) [na:na] at org.apache.http.impl.conn.PoolingHttpClientConnectionManager.connect(PoolingHttpClientConnectionManager.java:353) [na:na] at org.apache.http.impl.execchain.MainClientExec.establishRoute(MainClientExec.java:388) [na:na] at org.apache.http.impl.execchain.MainClientExec.execute(MainClientExec.java:236) [na:na] at org.apache.http.impl.execchain.ProtocolExec.execute(ProtocolExec.java:184) [na:na] at org.apache.http.impl.execchain.RetryExec.execute(RetryExec.java:88) [na:na] at org.apache.http.impl.execchain.RedirectExec.execute(RedirectExec.java:110) [na:na] at org.apache.http.impl.client.InternalHttpClient.doExecute(InternalHttpClient.java:184) [httpcore:0.0.0] at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:82) [httpcore:0.0.0] at org.apache.http.impl.client.CloseableHttpClient.execute(CloseableHttpClient.java:55) [httpcore:0.0.0] at org.sonatype.nexus.repository.httpclient.FilteredHttpClient$2.call(FilteredHttpClient.java:196) [org.sonatype.nexus.repository:3.0.1.01] at org.sonatype.nexus.repository.httpclient.FilteredHttpClient$2.call(FilteredHttpClient.java:1) [org.sonatype.nexus.repository:3.0.1.01] at org.sonatype.nexus.repository.httpclient.FilteredHttpClient.filter(FilteredHttpClient.java:99) [org.sonatype.nexus.repository:3.0.1.01] at org.sonatype.nexus.repository.httpclient.FilteredHttpClient.execute(FilteredHttpClient.java:192) [org.sonatype.nexus.repository:3.0.1.01] at org.sonatype.nexus.repository.docker.internal.DockerProxyFacetImpl.execute(DockerProxyFacetImpl.java:285) [na:na] at org.sonatype.nexus.repository.proxy.ProxyFacetSupport.fetch(ProxyFacetSupport.java:222) [org.sonatype.nexus.repository:3.0.1.01] at org.sonatype.nexus.repository.proxy.ProxyFacetSupport.fetch(ProxyFacetSupport.java:202) [org.sonatype.nexus.repository:3.0.1.01] at org.sonatype.nexus.repository.proxy.ProxyFacetSupport.get(ProxyFacetSupport.java:164) [org.sonatype.nexus.repository:3.0.1.01] at org.sonatype.nexus.repository.proxy.ProxyHandler.handle(ProxyHandler.java:48) [org.sonatype.nexus.repository:3.0.1.01] at org.sonatype.nexus.repository.view.Context.proceed(Context.java:79) [org.sonatype.nexus.repository:3.0.1.01] at org.sonatype.nexus.repository.storage.UnitOfWorkHandler.handle(UnitOfWorkHandler.java:39) [org.sonatype.nexus.repository:3.0.1.01] {noformat}
