TIE Failed to communicate with tie.gti.mcafee.com using Proxy

Jump to solution

Our ePO & TIE is not internet faced. So we created an ACL rule in web proxy to allow TIE server to communicate with tie.gti.mcafee.com. TIE is unable to contact GTI cloud, may be any configuration is missing on network configuration of TIE server.

If we tried to set our DNS under TIE network configuration then it reaching internal DNS to lookup tie.gti.mcafee.com URL -- result failed

If we tried to remove DNS entries under network configuration - By setting, IP, subnet & Default GW -- still it is failed.

please advise the steps to be configured on TIE server to reach GTI cloud via proxy ( our proxy is in DMZ - already 9090 port is in opened).

Thanks

There is a command to check connectivity between TIE & GTI cloud via proxy.

curl -kvx proxyip-add:9090 https://tie.gti.mcafee.com:443

This shows connection status, RSA_DES certificate details and communication status.

usually i tried to ping & nslookup.

I sent output of above command to platinum support to know the connection status. Received positive response from McAfee.

Also we can check on ePO console - reputation and GTI last communication.

my issue is resolved now.

Hi ​,

have you excluded TIE from SSL interception?? We are using McAfee Webgateway for TIE internet connections without any troubles.

Cheers

I solved a GTI communication issue opening all subnets of this article:

KB79640

Subnets change... so it's better to open all.
