Unable to Add Multiple Web Adapters Portal for ArcGIs 10.8.1

[SKW_UK]

Hi All,

We are building out our GIS, and are having a few "issues" with the web adapter.

We have 2x Web Adapters behind a Load Balancer, which is the "Entry point" for our GIS.  This will be something like https://gis.com/portal

We also have 2x portals configured in an active/standby mode.  These are connected behind a load balancer, but only for admin purposes, URL would be https://gisportaladin.com:7443/arcgis

Both the WebContextURL and privatePortalURL properties have been set with the details above.

The issue we are encountering, is that registering one web adapter, de-registers the other! so we can only ever have one web adapter registered at a time.

Am i missing a really simple step?

Thanks,

Steve

I had this exact scenario happen to me; what I had to do was on the 2nd server bind it to a different URL temporarily; when ran the Web-Adaptor Config process; then once the connection was made change the binding/url back.

Then I went into the PortalAdmin and did a Update on that Web-Adaptor record to reflect the URL.
