Proxy Repositories remote unavailable due to ssh handshake exception

Hi All,

We are facing difficulties with keeping proxy repositories online(Remote available). The repositories fail to connect with remote showing
We have trusted the certificate by going in to repository > View Certificate > Add To TrustStore.
But this process is temporary solution as it lasts for only a day at max and we have to repeat same step daily. Our nexus is behind firewall so it connects remote through proxies. Please guide us in making it permanent.

This because your Nexus instance is configured to use an HTTP proxy server that rewrites SSL certificates for secure ( HTTPS ) remote hosts. This is why importing the certificate works temporarily.

See the following article that shows a permanent solution.
