Config Locked Error

I received an error of Config Locked on a device. It had been offline for a period of time and began updates of firmware upon power-up. How long do should I expect to have the device locked before it has been troubleshot by Peplink? Has anyone dealt with this before?

Current Firmware 8.5.3 build 5298 attempting to upgrade to 8.5.4 build 5407.
