Two Machine Deployment - WebD Issue

[Jim Gill]

Hello All

I have recently deployed FMS 20.3 on an Ubuntu  22.04 Linux machine.  In a single machine deployment everything works as expected with no errors.  WebD users login through the API with a PHP script fired from my website.  All good.

I was told by a developer that I would get better performance for my users by setting up a Primary/Secondary machine deployment.  So I followed Claris's guide to installing a second machine guide (https://help.claris.com/en/server-installation-configuration-guide/content/installing-on-a-secondary-linux.html) and was abled to configure the secondary machine, install SSL and connect the two machines. 

All said - pretty easy - BUT: WedD users can't login.  They get 502 Bad Gateway - nginx.  Both primary and secondary machines are on the LAN side of my firewall.  I even tried NAT-ing WebD connections to the seconday machine but this produced 405 Not Allowed.

Is there something I'm missing?  Any suggestions?  As always - much appreciated for any help.  This forum is one of the reasons I continue to loves Filemaker!

Thanks - Jim
