Blink sync module

My Blink cameras and doorbell were working fine before we switched back to Xfinity internet. I got the cameras connected but not the doorbell. Thought maybe it was dead and ordered the newest doorbell camera which came with a sync module. I have stayed on the phone with Blink for way too long and it's still not connecting. I have looked at some of the posts here and verified the Bridge mode was turned off, turned off both the 5 and 6 GHz. Still won't connect. It finds the sync module but then says it cannot connect to the Blink servers and says the most common problem is the password. I have double checked and even re-entered the password. We just got a new tv and the night before I called Blink last week, I entered that password at least a dozen times setting everything up on that new tv so I KNOW that is not the issue. I have probably tried to connect over 50 times. I have unplugged and reset both the gateway and the sync module multiple times. I don't know what else to try at this point and am very frustrated with both Blink and Xfinity. They had me try to use my tablet instead of my phone and I still got the same message. This appears to be a known issue so surely the answer is also known.
