Fully customizable deployment keeps failing

Hi Folks

While i am able to deploy the maximum and large templates successfully, when trying the customized option, we keep failing at the controller VM with the following error message:

Please let me know if this is common and if there's something wrong that we are doing. The options we are choosing are quite standard and it should deploy without any problems. MySQL DB, GlusterFS, WAF as the gateway with no HTTPS termination at the moment.

Let me know if any other details may be required. Region of choice is Southeast Asia.

Thanks
