N2WS 3.x - Backup may fail with "could not get object from aws. Reason: SSL validation for <Host> [SSL: CERTIFICATE_VERIFY_FAILED]"
Running backups may fail with the following error:
ERROR: run_snapshots(agent.py:1796) (instance: i-1234567) could not get object from aws. Reason: SSL validation failed for https://ec2.us-east-1.amazonaws.com/ [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed (_ssl.c:661) (UnknownError)
This issue usually occur due to firewall, gateway or proxy interrupting or replacing the certificate for the API calls.
You can test if it is some Firewall that causes the issue by connecting to the N2WS instance (user is cpmuser) and trying to run this commands:
- curl -v https://ec2.us-east-1.amazonaws.com (you need to replace "ec2" with the endpoint in your error message, and "us-east-1" with the region in your error message)
- aws ec2 describe-snapshots --owner-ids self
If any of the commands fails with same SSL issue, then the problem is in the network (firewall, proxy,etc...) and not with the N2WS server.
