SSLHandshakeException trying to reconnect target sites

[racom]

We run vSphere Replication Appliances 6.1.1.13216 Build 3849281 in two vSphere 6.0 datacenters. I tried to configure replication for new VM but login to remote site failed with "The site is not accessible. Try to reconnect the site from the Target Sites view." error. An attempt to reconnect target site fails with "javax.net.ssl.SSLHandshakeException: Remote host closed connection during handshake" error on both sides. I can ping VRA each other and nslookup works well. Existing replications work. Credentials to both vCenters work.

Reboot didn't help and I can see this message in /var/log/boot.msg (on both VRA's):

cannot (un)set powersave mode

Suspicious exit code from reguiplugin: 1

Exception in thread "main" (vmodl.fault.InvalidArgument) {

   faultCause = null,

   faultMessage = null,

   invalidProperty = extension.extendedProductInfo.companyUrl
