Interesting. Have you attempted a restart of elasticsearch on the nodes yet? If not, the step I would recommend next is restarting important NLS services on both nodes:

So sorry for the late reply. Had to be out of the office.
This is all working fine now. We had our month patching and the servers were both rebooted. Everything is working fine now. Both instances show up normally. Just took a full server restart, not just stopping and starting elasticsearch. Weird but it worked.
No worries - glad to hear it's all working. I'll lock the thread.
Thanks!
