Portal for ArcGIS WebAdaptor Configuration Error

[OmolaraKareem]

Hello,

I am try to configure a webadaptor with my Portal for ArcGIS and I keep getting the error message below. Can anyone tell me why? Particularly because I have done it (WebAdaptor configuration) before and it (the Portal) worked for several months, until last week when it just stopped working. While trying to trouble shoot, I uninstalled the webAdaptor, then reinstalled, that is when i get the error message.

Hi Jayanta,

Thanks for responding. I know the Portal can be configured with the Web Adaptor using an initial Administrator account and I have done so without any problems in the past. gisportal is the initial Administrator.

But now, for some inexplicable reason, it just stopped working last week

I've seen this with server multiple times and restarting the server service helped.  I would restart the Portal for ArcGIS service.  If that doesn't solve the issue, restart the machine hosting Portal.

To restart the service, type services.msc in the windows search box.  Find the Portal for ArcGIS Service, highlight it and click restart.

Hope this helps you with your issue.

Hi Steven.

Thanks for responding. I have done both your suggestions in the last few days since this whole problem began. I tried that first and when that didn't solve the problem I uninstalled and then reinstalled the Web Adaptor, thinking that might be the problem.

Could you take screen shots of what's in your IIS managers Default Web Site - Authentication and the Bindings.

I hope this is what you need.

That's what looks like should be there.  Could you open the https binding (highlight and click edit) and check to make sure the ssl cert is there.

Thanks, Everything looks fine there.

The only other thing I can think of is you aren't specifying the correct administrator credentials when configuring the web adapter with portal or your Anti-Virus is blocking the website from loading.

This may need escalated to Tech Support.

Thanks so much Steven. I will escalate as you have suggested, cos I'm at my wits end right now.
