Unable to connect Chamberlain garage door opener via 5g internet

Hum, over the weekend MyQ started working again as my opener connection indicator is solid green.  Still connected this morning.  I took no action with either the app nor the router.  

I had the same issue today and upon digging further, I was able to correlate my issue to the current version of firmware on the Nokia device.  It automatically updated 23 days ago and that was exactly the same time the MyQ app was saying it was offline.

I proceeded to reboot the modem with no change.  I think learned the MyQ to a phone hotspot and it worked fine so I knew the issue was with the T-mobile ISP service.  I then tried to reconnect the MyQ to the T-mobile and it still didn't work.

The final step that fixed my issue was to perform a factory reset (not just reboot) on the Nokia modem from T-mobile.  I am happy to report that it my garage door is back to working normally now.

Thanks Shivaslrons. I ended up setting one of my laptops up as hotspot and connecting that way for now. Hopefully they'll come out with a fix soon!

i spent time with T-Mobile support last Wednesday.  The tech acknowledged that the Nokia router does not have port forwarding active at this time.  there are efforts in work to address this 'feature' which is causing MyQ to not connect.  No ETA on the 'fix'.  

I'm having the same issue since switching to T-Mobile internet. MyQ will not connect. Everything I have works fine. Aside from myQ the internet is fantastic. 
 

I spoke to Chamberlain they blamed T-Mobile router settings… which we have very basic access everything advanced is locked down. 

Still having issues.

Configured one garage opener to use the HotSpot on my TMOBILE cell phone, the garage door works fine in MyQ app.

The other garage door thats on the TMOBILE home WiFi still doesn't work.

TCP 8883 is blocked either in, out or in both directions on the TMOBILE home router

Interestingly, this evening i can operate my garage door via myq app.  I took no action.   do any of the posters on this thread experience the same change?

My original gateway worked well with the Chamberlain door and MyQ app. It was when the T-Mobile gateway was replaced due to its buffering and freezing issues that it no longer connected. T-Mobile claims nothing changed between the gateways. Replacement was a refurbished unit, the same model.

This is an update to my original post. 

My opener has never connected to the myq server due to blocked port.  I have been on tmobile home internet for around two weeks.  

Having the same issue. Both of my Chamberlain garage openers worked fine up till 36-48 hours ago and then became unreachable in the MyQ app.

I figured TMobile changed something, like a blocked port (i.e. 8883). 

To test this, I reconfigured the Garage openers to use my Verizon Hotspot and everything worked fine.

Looks like Tmobile added some filtering.

Please fix this or give us the ability allow exceptions on the router.
