Web service stops pushing status updates after connectivity loss

[bash1979]

I use the web service option for integration with SmartThings. Lately, I've noticed that, if there is any interruption in connectivity (i.e. internet outage, router reboots, etc), the web service stops pushing status updates (even though it still responds to pull requests from SmartThings). So automations around motion or door open/close events no longer work because the updates aren't be pushed. The only way to fix is to reboot the SmartThings Hub and restart the OmniLinkBridge service (in that order).

The last entry in the log file is below. Anyone else seeing this?

I am experiencing similar loss of connectivity. Everything will work fine for about 10-15 minutes, and then it stops working. OmniLinkBridge is continuing to get status updates from HAI, but I am not seeing anything in the live log on SmartThings.
