GCP Pub/Sub subscription not receiving messages after migration to new region
I've been struggling with this for a few days now and could really use some help. I've recently migrated my GCP project from the us-central1 region to us-east1, and since then, my Pub/Sub subscription is not receiving messages. The publisher is successfully sending messages to the topic, but the subscriber does not seem to receive any. I checked the IAM permissions and ensured that the service account used by the subscriber has the 'Pub/Sub Subscriber' role. Here's a snippet of my subscriber code: ```python from google.cloud import pubsub_v1 project_id = 'my-project-id' topic_id = 'my-topic' subscription_id = 'my-subscription' subscriber = pubsub_v1.SubscriberClient() subscription_path = subscriber.subscription_path(project_id, subscription_id) def callback(message): print(f'Received message: {message.data.decode()}') message.ack() streaming_pull_future = subscriber.subscribe(subscription_path, callback=callback) print(f'Listening for messages on {subscription_path}...') try: streaming_pull_future.result() except Exception as e: print(f'behavior: {e}') ``` Despite the subscriber being active, I'm not seeing any output or errors in the logs. I also verified that the topic and subscription exist in the new region, and the messages being published are indeed intended for that topic. I have tried deleting and recreating both the topic and subscription, but the scenario continues. Is there something specific I might be missing in the migration process, or any configuration I should check? I'm starting to wonder if there's a region-specific setting I overlooked.
