the requests suddenly stopped and I don't know why this happen. I am using java11.

enter image description here

this my app engine configs

<precompilation-enabled>false</precompilation-enabled>
<sessions-enabled>true</sessions-enabled>
<threadsafe>true</threadsafe> 

<instance-class>F4</instance-class>
<automatic-scaling>
    <max-concurrent-requests>50</max-concurrent-requests>
    <max-pending-latency>8s</max-pending-latency> 
    <min-pending-latency>4s</min-pending-latency> 
    <min-instances>1</min-instances>

Error you're getting means as per documentation that the client disconnected before load balancer could reply:

client_disconnected_before_any_response - The connection to the client was broken before the load balancer sent any response.

And the Error code 123 is a Deadline Exceeded Error

HARD_REQUEST_TIME_LIMIT- Request exceeded a deadline, causing the instance to shut down

Here are some known issues that cause this issue:

  • High latency, this means that your startup code for instances may take too long, what is recommended in this case is to set a “min_idle_instances” just remember that this might cause an increase in your billing.
  • Running multiple requests in parallel, this can cause a thread deadlock and result in timeouts; in this case it is recommend to use load balancers.

As also mentioned in this stackoverflow Answer by LundinCast

  • You've most likely set your App Engine service scaling element to "autoscaling" (or didn't define it, autoscaling being the default value) in the app.yaml file.
  • Instances in autoscaling have a deadline of 10min, as documented here. You'll need to re-deploy your service with an updated app.yaml file setting the scaling element to "manual scaling" or "basic scaling" to allow your tasks to run to up to 24h.
