    Hello,

    What files need to be configured to allow for unauthenticated proxy server set for third party API (Mimecast) to connect to eu-api.mimecast.com?

    I have currently set /etc/httpd/conf.d/ssl.conf and  /opt/qradar/dca/server.ini as outlined in this KB IBM QRadar: X-Force Frequently Asked Questions (FAQ) - Updated - United States

    What do I need to know and what are the frequently asked questions about the QRadar X-Force Threat Intelligence feed?

    Extract from QRADAR Log

    Unexpected exception raise while testing connection: Unexcepted error connecting to API.

    Exception: HTTPSConnectionPool(host='eu-api.mimecast.com', port=443): Max retries exceeded with url: /api/audit/get-siem-logs (Caused by ConnectTimeoutError(<requests.packages.urllib3.connection.VerifiedHTTPSConnection object at 0x3398f50>, 'Connection to eu-api.mimecast.com timed out. (connect timeout=30.0)'))



    Thank you.

    Shjajad,

    I was just writing up an article around this issue, but you did not mention your QRadar version. This is typically something we'd try to resolve via the QRadar Support forums (https://ibm.biz/qradarforums), but if you are on QRadar 7.3.2, see this article: QRadar 7.3.2: How to tune proxy configurations for app containers.

    If you are on QRadar 7.3.2, this issue as described in the article I wrote above outlines apps in QRadar 7.3.2 can inherit the proxy configuration from the Console config, which can replace the proxy config for the app itself and preventing the app container from reaching out to an external data source.  


    If you are on QRadar 7.3.1, using IPv6 in your network, or having app issues related to the QRadar proxy, you might consider opening a case on this issue here: https://ibm.com/mysupport.  

    Hope this help, let me know if you have further questions or concerns. The best place to get quick answers is the QRadar Support forums for these types of issues or by opening a case. We keep a closer eye on the support forums, you can find those here: https://ibm.biz/qradarforums

    Extract of reply sent do Jonathan inadvertently...

    Hello Jonathan,

    Thank you for the reply.

    I went through you, although the steps to get to the diagnosis were different - having determined the app id is issues /opt/qradar/support/qapp_utils_730.py connect xxxx .  Where xxxx = app id.

    We have version 7.3.1 and do not have a IPv6 network.

    I don't see any errors being listed in the APi Logs and we have also setup explicit Firewall rules to allow access to the two https site.  However, still not having any success in connecting to the destination site to pull Mimecast logs down.

    Any further thoughts please?

    Thank you.

    Another point to mention is that I'm not seeing any outbound packets to the destination aside from dns lookups between QRADAR and our DNS box.  Nothing else is captured through tcpdump.

    Regards,
