8. Please describe the issue.

I have installed Flex TV without incident. I opened up port forwarding for several ports with each forwarding to 80. I set the public address to myPublicIPAddress:80. All of that is fine. However, when I click LINK GOOGLE, I receive a 502 error from Google indicating "The server encountered a temporary error and could not complete your request." It's important I figure this out as it's not even for me. I'm trying to come up with a completely hands-free solution for my 99-year-old grandmother. Her vision and hearing aren't great, but the biggest problem is her agility. She can no longer operate a remote control. I have built an entire library on Plex of all her old DVDs. I want her to be able to pull them up with her voice via Google Assistant. Please help. I appreciate it. If you need any more information to help resolve this matter, please let me know ASAP. Thank you.
