Any chance you have something along the path that causes the
connectivity issues?
What's the network connectivity between this node and the other node?
Can you try transferring a big file between the two servers? perhaps
you have an MTU issue that causes TCP PMTU discovery fail.
Can you send large pings between the servers? try pinging them from
both sides with large packets (5000, 1).
