Describe the bug The relay proxy logs keeps showing Unexpected error while sending events: Post "https://events.launchdarkly.com/diagnostic": context deadline exceeded (Client.Timeout exceeded while awaiting headers) even when there is 0 connection to this relay proxy. To reproduce relay proxy 6.6.4 is deployed as a GCP cloud run service. The configurations are mostly used default value, we only configured AUTO_CONFIG_KEY, and USE_EVENTS and route the traffic to a proxy that will connect to our company squid proxy that egress traffic to LaunchDarkly.

        env:
        - name: AUTO_CONFIG_KEY
          valueFrom:
            secretKeyRef:
              key: '3'
              name: [gsm_key1]
        - name: https_proxy
          valueFrom:
            secretKeyRef:
              key: '3'
              name: [gsm_key2]
        - name: http_proxy
          valueFrom:
            secretKeyRef:
              key: '3'
              name: [gsm_key3]
        - name: no_proxy
          value: .run.app,.googleapis.com
        - name: USE_EVENTS
          value: 'true'
        resources:
          limits:
            cpu: 2000m
            memory: 8000Mi

So the relay proxy is running fine, we did test by checking flag data using the relay proxy, and we also try to send events, which is also working fine, but this logs seems a bit annoying and not sure why it is keep popping up, even though there isn't any request to send events, and we are not sure at this stage what this error really indicated. Expected behavior A clear and concise description of what you expected to happen. No error logs shows that related to requests to events endpoint

Logs If applicable, add any log output related to your problem.

SDK version NO SDK is used, just using curl for testing purpose, but this error shows regardless if there is request or not.

Language version, developer tools For instance, Go 1.11 or Ruby 2.5.3. If you are using a language that requires a separate compiler, such as C, please include the name and version of the compiler too.

OS/platform CloudRun

Additional context We have raised a support ticket https://support.launchdarkly.com/hc/en-us/requests/19498 but it's been 20 days, and the last reply from the support is they are still looking into it, so want to try here to see if there is any luck.
