nexus.onap.org resetting connection on sdnc merge jobs

Havent been able to build release version of SDNC for several days despite repeated attempts.

Error message is usually something like this:
18:46:47 [ERROR] Failed to execute goal org.sonatype.plugins:nexus-staging-maven-plugin:1.6.7:deploy (injected-nexus-deploy) on project sdnc-oam: Failed to deploy artifacts: Could not transfer artifact org.onap.sdnc.oam:platform-logic-installer:zip:1.4.0-20181002.184326-145 from/to ecomp-snapshots (http://nexus.onap.org/content/repositories/snapshots): Connection reset -> [Help 1]
