Hello,
As far as I know, the AWS Load Balancer is an L7 load balancer, which adds the X-Forwarded-For HTTP header to forwarded requests. Additionally, the LB IP seen by WebADM may not be fixed, so you cannot configure just the IP in webadm.conf. WebADM will not accept forwarded requests if the LB IP is not known in its configuration.
I recommend configuring the reverse_proxies setting in /opt/webadm/conf/webadm.conf to auto, as described in the following documentation:
https://docs.rcdevs.com/endpoints_and_publication/
After making this change, restart the WebADM services for it to take effect.
Then, in the PWReset app configuration, make sure to check the box "Publish on Reverse Proxy/WAProxy".
After that, it should work.
Regards,
