# Error associated with HTTPSConnectionPool

How can I solve this situation?

I'm using the IBMQX2 chip. When I run my simulation some circuits are executed and the following WARNING message is displayed:

account._job_result_object_storage:WARNING:2020-09-10 05:31:30,318: An error occurred while sending download completion acknowledgement: "HTTPSConnectionPool(host='api.quantum-computing.ibm.com', port=443): Read timed out. (read timeout=None)"


After a long time a few more circuits are run and the following error message is displayed:

IBMQBackendApiError: 'Error sending job: "HTTPSConnectionPool (host = \ 'api .quantum -computing.ibm.com \', port = 443): Reading timeout. (reading timeout = None) ".


At this point, the entire simulation is permanently stopped. When I used Windows 10 this type of message did not appear but, recently, I changed the operating system to Ubuntu 20.04. I don't know if it is necessary to do some kind of configuration on Linux.

• Hi and welcome to Quantum Computing SE. Could you please add more context? Whne this error occurs, for example? Sep 10 '20 at 6:39
