alteryx AWS ALB SSL

[mqc]

I need to set up alteryx server gallery to use SSL and allow our users to connect through an application load balancer. I've configured an ssl cert on the ALB and have a self signed ssl cert on the alteryx server (for the time being) however I can't open the gallery while using the alb dns name. It works fine if I use the server FQDN. When accessing it via the ALB, all I get in chrome is "

Analytics Gallery

Loading...

whereas if I use IE, it just shows a blank page. Is this because the SSL and dns names are for the ALB and alteryx server itself are different? If so, is there any way we can have a SSL cert for the servers FQDN but still use something like https://alteryx-gallery.somedomain.com ? I tried changing the friendly name in MMC with the above setup to alteryx-gallery.somedomain.com but that did not change a thing. If I use https://alteryx-gallery.somedomain.com in the gallery URL config the service fails to start even if I have a SSL cert (self signed at this point) for this url

Looking at the console in chrome, there's a lot of 400 errors

Hello,

I have a Gallery with similar configuration and users are complaining because of a lot of HTTP 400 errors.

My Gallery is being an AWS ALB. I have an SSL cert on the ALB and a self-signed on the gallery server. 

Were you able to resolve your problem and if you don't mind sharing what did you do I appreciate it.

Thank you,

Mario.
