Relatively new user. Currently running 2.2.7.128 on my c7. I keep running into the “No response from hub” error when trying to use dashboards in the mobile app. I’ve seen similar issues reported previously. I’ve setup a dhcp reservation for my hub and verified I’m seeing no other network issues. I can fix this issue with a hub reboot, but see the same problem come back after waiting pretty much exactly a week. Any advice on what else I can look at? Support ticket my best option? Pretty frustrating that it breaks the app so I have to be home to fix it and get things working again. Any info or troubleshooting steps would be greatly appreciated. Thanks.
When the issue occurs, is there anything in the logs? If so, please post a screenshot as it might help find the source of the issue.
Nothing I’ve found that stands out in the logs. The issue is currently happening, so if there is anything I can do to help troubleshoot then I’m happy to do so. Just seem to lose connection to the cloud a week after reboot. Thanks for the response. Appreciate the help.
Have you tried to see if you can reach the Diagnostic Tool before rebooting? If so, did you run a Soft Reset?
Issue is currently happening. All local access and automation is fine. I can get to diagnostics without issue. I’ve been doing “reboot hub” in settings to resolve the problem temporarily but have to be home to do it, I haven’t done a soft reset from diagnostics though. Should I do that now? Wasn’t sure if there was anything else helpful I could do while broken. It’s broken 3 weeks in a row right at the 1 week mark each time. Again, appreciate you looking at it.

Go ahead and run the Soft Reset, and see if that helps.
Soft reset then restore from backup?
Yes.

@bobbyD I did a soft reset and a restore followed by a reboot. Things are working again and I’ll monitor for the next week to see what happens. Please let me know if there is anything else I should do or check out in the meantime. Thanks again to everyone that has responded and helped.

Sort of curious if rebooting your router would make things work again.
What brand/model is your router?
Tp-link c5400. I’m able to access the hub locally without issue on the dhcp reserved IP address even when experiencing this problem. Makes me think the issue isn’t the router? Can definitely try a reboot of the router next time if it would be helpful.
I don't think we can say either way? Maybe traffic is routing fine Intranet but not Internet?
But hopefully that soft reset fixed it. Guess we will find out in a week or so? So odd that it is almost exactly a week...
Thanks for the ideas. Other cloud based services through the same router seem fine (Wyze cams, August locks, etc.). And the fact that local connectivity on the same IP seems ok makes me think it isn’t specific to the router, but I agree that something is going on. If this is an outbound initiated but 2-way connection, then I’m not sure what else to check. I hope the soft reset fixes it, but open to any additional troubleshooting steps that might help figure out what I’m seeing. Seems like others have seen something similar, but I haven’t seen a root cause discovered.

2.2.8.143 added three endpoints to hopefully deal with this scenario. It's not reproducible for me, and never been, so it's sort of a band aid that deals with symptoms. Hopefully it addresses the issue, though. If it does, I'll add proper UI to Settings/Networking. The endpoints are below, there are no parameters, and their names are self explanatory. Hitting enable/disable endpoints makes the setting effective immediately and forwards to status endpoint to display current status.

Thanks for the update. I’m sure it is a tough one to tackle if you can’t repro it. I’m happy to help provide logs or any info I can to help resolve it while it seems to be happening consistently if that would be helpful. I can upgrade and enable this to likely work around the issue, but don’t mind staying in my current state for a bit if it allows for a potential fix to the root of the issue. Just let me know.

Soft reset didn’t make a difference. Same thing after exactly a week. I updated and enabled the reconnect and will report back in a week.
@gopher.ny It looks like the work around is working. Over a week and I’m not seeing this error. Let me know if there is anything I can do to help determine root cause, but it looks like I’ll be fine as long as I have the workaround turned on.

Thank you for confirming this!
I found the root cause, and created a cloud based workaround, which makes the issue manifest in 4 weeks instead of 1. Turns out, reconnect logic doesn't actually do anything meaningful to resolve the problem at hand 
2.2.9 will have a permanent fix.

Is this the same issue that affects some Alexa integrations?
