Customer comment (moved from #445): We are seeing issues on v9.1.0 of the agent (with 1.5.0 f5-common-python) with certificate verification failures in the case we use self-signed/unverifiable certificates. The specific issue seems to be here https://github.com/F5Networks/f5-common-python/blob/v1.5.0/f5/bigip/__init__.py#L82 and if we patch to response = connect.get(base_uri, verify=False) it resolves the issue.
