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

Are the 2x Web Adaptors on the same Web Server, or separate Web Servers? The configuration you are describing generally works well when the WAs are on separate Web Servers.

Hi Loren,

It is on two separate web servers, as we are removing single points of failure.

Many Thanks,

Hi Steve,

Try registering the first WA, set the Webcontext URL and then configuring second WA in this order.

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.

Thanks Steve. I think what @ShaneMiles says below is the key. I reviewed notes from a previous implementation for a client of a Highly Available ArcGIS Enterprise, and found the same steps: After the other necessary prerequisites (e.g. certificates, load balancer setup, shared file server content directory, the Portal installs, etc, etc), .1 install and configure the first Web Adaptor, 2. configure Portal's Web Context URL and Private Portal URL, 3. install and configure the second Web Adaptor. The order of those appears to be critical for success.

Hi Shane,

That is the exact approach I have taken.

Hi Loren, thanks for your reply, but the order of steps mentioned, is the exact same order I have taken.

Many Thanks,
Steve
