PowerShell - The function stopped run Function App

[DeV1L]

The function was working for a while. Suddenly it stopped run on the schedule. But it run manually well. The only way I've found to fix it temporary it's stop and start (not restart) whole application in the portal. But it helps only for a day o two.

Support team told that PowerShell function with 1.x runtime is experimental and they can't help.

function.json

{
  'bindings': [
    {
      'name': 'myTimer',
      'type': 'timerTrigger',
      'direction': 'in',
      'schedule': '0 0 3 * * *'
    }
  ],
  'disabled': false
}
