Web Adaptor (IIS) 10.9.1 - Portal displays blank page

AnthonyRyanEQL

Hi all,

I just installed Portal for ArcGIS 10.9.1 and the IIS Web adaptor. Configuration, etc was successful.

When I go to access Portal via the webadaptor url it now displays a blank page. If I use the standard server address:7443/arcgis/home url, the portal page opens as expected.

Have seen a previous post relating to clearing cache, site data, etc. Done this with no success.

Has anybody come across this issue in 10.9.1?

Thanks

The reason for the blank screen relates to which authentication method is enabled in IIS. By default when installing a WA for Portal, only Windows Authentication is enabled and Windows & Anon Authentication is enabled from Server sites (which work).

After going into IIS and enabling Anonymous Authentication for the Portal WA's virtual app, I am able to now reach Portal via the WA url.

Thanks for helping me with different things to check

In the first instance try to access the page using "In Private Mode". No caching of anything there and a great test tool. If you go to the machine with IIS, what happens when you type:

https://sub.domain.com/portal/webadaptor

https://sub.domain.com/portal/home

Then try the second from a remote machine. The webadaptor URL is only available on the IIS machine itself.

Also ask different people to review as well. I've completed a development upgrade and a production new build this week with no issues.

Scott,

Thanks for the reply.

First url on the IIS machine gives the webadaptor configure page

Second url on the IIS machine gives me blank page

First url on remote machine (eg. my desktop) gives me the expected error relating to be run on the local machine

Second url on remote machine (eg. my desktop) gives me blank page

What happens if you use Developer tools. What traces and responses can you see in the Network Tab?

AnthonyRyanEQL

To me it looks normal - No obvious problems/errors

It has elements

Has Network information with all status=200

No errors

Also,

I added another webadaptor for server and all is working as expected
