IME, connection resets are most often due to network/firewall rules that block the traffic. Might be the case here.

Yes Correct @reamon, I have already informed the network team to check on this issue.

Hello, @reamon - For this issue our network team made some changes S3 format [region/bucket name] may not be enabled so they have allowed it now but still we are getting the same error.

Any thoughts on this?

This can sometimes be a challenge, but if something along the network path is blocking the traffic within your network, the network team should be able to see what the firewalls are doing to that traffic (allow, deny). Shouldn’t have to guess or trial/error as inferred by the “may not be enabled” Should be able to know for sure one way or the other.

You have two types of urls for S3:
Global ones: {bucket-name}.s3.amazonaws.com
Regional one: {bucket-name}.s3.{region}.amazonaws.com

I’ve had once issues with the global one being blocked, but the regional one was working, because of network policies.
That was with integration runtimes deployed in AWS.
