General Alexa (Echo) issue

All my Amazon Echo’s (except two spot’s) stopped working in the last few days. However my HA integration to them still works. Meaning I can send any audio from HA and get it to play on the Echo device. However when I go to speak with the same Echo to give it a voice command it flashes red and says “I’m having trouble understanding right now”. The Internet has been no help troubleshooting as all the recommendations say to check network/wifi connectivity. I know they are connected because I can see them on my AP’s, I can see traffic through my firewall and HA can send them audio. Just figured I’d check here to see if anyone had any ideas?
