I’m calling an HTTP API endpoint hosted on AWS EC2: request_start_date = “2020-01-01”
request_end_date = “2020-03-01”
sessions_response = requests.get(f’http://{API_ENDPOINT}/sessions?start_date={request_start_date}&end_date={request_end_date}')
print(sessions_response.status_code), and got the following error: ConnectionError: (‘Connection aborted.’, RemoteDisconnected(‘Remote end closed connection without response’)) when checked into the EC2 instance I got the following error
Hi, @P4RM can you restart the lab and see if the error still persists?

Hi, I’m having the same issue, reboot for few rounds, also reboot the EC2 instances. Everything is still the same. Same error.
Hi @CheeHaw can you please try this solution and see if that helps
Hello @Tan_Quoc_Bao_Nguyen ,
This error happens when the lab server reboots when you terraform apply. You could wait for a new lab session to clear those resources or they could be deleted manually from the AWS console. Thank you:
Select de-c4w4a1-connection-rds from AWS glue > connections and delete:
[C4W4A1_rds_connection]
Select de-c4w4a1-glue-role from IAM > Roles and delete and type the role name:
[C4W4A1_iam_glue_role]
