Internet Gateway 828LM with error code 309

My internet gateway 828LM has been working flawlessly for about 2 years and now it's showing error code 309 with both garage door openers in offline status and the green LED is flashing repeatedly.  I have tried to reboot router/modem, reset the 828LM, remove the 828LM from myliftmaster.com account, then added it back along with the openers and it worked for about a week then the devices are offline again.  Has anyone had similar issues lately?

Mine did that last week (Dec/10-15/2018) and of course, no one knew wtf was going on.
I did a router reboot, modem reboot, 828LMfactory reset to no avail. Even swapped ethernet cable on the router for another port, still nothing.
I left it unplugged (powered off) for the rest of the day and gave up.
The next day, I found a post from another user mentioning that LiftMaster had moved their servers to AWS.... without telling anyone .. (don't know how this user found it).
So I plugged mine back and it went solid green right away (after a few handshaking flashes).
I had to pair it again with my door opener - not sure if because I hard reset it or the AWS migration was flawed and deleted the device from my account.

The lesson learned is that if the little box cannot reach the server, it will blink forever.... and I still am not sure if the blinking means it is retrying... 

So, if your computer is talking fine with the internet, and you switched the 808LM cable to another router port, then it is not being able to talk to the server...
You can also try a hard reset (factory reset): pull the power plug, wait a few seconds, press the reset button with a paper clip (there is a little hole on the side); hold it pressed; plug the power back on; hold for 20 seconds more and release: the 828LM should be factory reset.

If still fails to go solid green, I'd still try to leave it powered off for another day and retry.

You may have to pair it again.

After that...... well, maybe it went bad, but I think it's a coincidence.

Thanks for the advice.  I have done the reset couple times already and it didn't help.  This morning, I've checked again and everything was back online.  Then in the evening, it went offline again.  It must have something to do with their server.

Yeah... I agree that is probably the server side. Unfortunately, on our side we can do nothing. Not sure if they are even monitoring their email for support since this service seems to be a freebie.  The previous time I had the this problem was several months ago and I actually emailed support; they finally told me that one of the servers had crashed.

I would love to have my own little server running on Tomcat and have independence of this scenario. And, of course, not depend on theirs as they could start charging us for the service at anytime....

I have a big system, it’s not working, I’m good at networking it’s not on my end. It’s a major PROBLEM.

The service isn’t free, people are paying for google and ifttt.

Has a solution for this been confirmed?

I can't confirm or deny but seems to be working - I haven't had any failures; however, since the last major outage, it has been slower than before. I guess that's because the servers on AWS are slow (or the hired service is barely below what is needed).
Mine still connects but sometimes, it takes those extra seconds that make me cringe.
