I had your other topic on this issue bookmarked to respond to when I had a chance. In it you said:
So, you’ve moved back to your ISP router from your new Nighthawk XR1000, and now you’re having the same issue with it as well? Has anything else changed with your configuration, other than swapping the routers in and out? What is the result if you disable relay in:
Settings -> Network -> Enable relay
Also, you may want to clear you DNS cache on the client system in case your public IP address has changed and the client has the old one cached. If the Chrome client you are testing is on Windows, you could try ipconfig /flushdns from the command line.
Finally, is this a remote client you’re testing, or is it a local client which is being forced remote due to some other issue (DNS rebinding protection)?
