We are trying to configure the Microsoft Cloud Services addon and are behind an NTLM proxy. From what I can see, the MS account and input are configured fine, however we are getting errors in the splunk_ta_microsoft-cloudservices_azure_audit.log along the following lines and no data is being ingested.
ConnectionError: HTTPSConnectionPool(host='login.microsoftonline.com', port=443): Max retries exceeded with url:
On checking the connections I cannot see this even making connections with our proxy, even though we have configured it via the proxy tab in the addon and is configured normally via the splunk-launch.conf file system wide. For fun I did remove the entries in the addon proxy tab but that made no difference.
