Hello Andres, I can definitely understand why this can be tricky to narrow down. From my research, it seems that this problem can be caused by several different factors that are unrelated, which makes it harder to troubleshoot. With that in mind, I did find that two possibilities seem to occur more frequently than the rest.
The first is that your app may be trying to write to the local disk <https://github.com/eggjs/egg/issues/3756>, which isn’t supported in GAE Standard, only writing to the /tmp directory is allowed <https://cloud.google.com/appengine/docs/the-appengine-environments#comparing_high-level_features>. Another option is that App Engine is timing out while waiting for a response <https://serverfault.com/questions/778213/appengine-stuck-on-updating-service-default>, possibly related to the communication between App Engine and Cloud Scheduler. We would need more detailed logs to better narrow down the issue, however based on the logs shared in the other group posting <https://groups.google.com/forum/#!msg/google-appengine-go/jeXkj0TBdQk/Enq0j2bZCQAJ>, if you are also observing “Waiting for network connection” messages, then it may be more of a timeout issue in this case. I hope this information helps point you in the right direction and please feel free to reply with any follow-up questions.
