Enterprise 11.1 webadaptor error

[vtey_esriau]

I am struggling to get the webadaptor for ArcGIS Enterprise 11.1 working. Please see  the error below. Please note the following

• Tested 11.0 and it works however 11.1 failed with the error shown below.
• Fresh install, win server 2022
• I attempted to use 11.0 web.config with 11.1 and doesn’t work either.
• I noted they look every different between 11.0 and 11.1

There are new prerequisites at 11.1 that must be applied.  Not needed at 11.0 or before.

Have you applied these?  I can confirm I've upgraded two clients from 10.9.1 to 11.1 this week and no issues with Web Adaptors - though they were using Server 2019.

Hi Scott. Which version of the hosting bundle did you use for your successful upgrades? I am using 6.0.18 hosting bundle found here - Download .NET 6.0 (Linux, macOS, and Windows) (microsoft.com).

The link in on the esri documentation to .net 6.0 does not work. 

I can't get  the web adaptor 11.1 to install as i get this error - 

I think it has to do with the dot net 6 version not being picked up by the installer?

thanks

good to know that 6.0.18 is available.  I was using 6.0.16.  Have you installed webdeploy as well?  I used v 3.6

Hi Scott. Thanks for the reply. I did have web deployed installed also. Turns out the issue was actually with McAfee blocking one of the web adaptor processes due to it having a ‘suspicious double file extension’ for anyone else having this issue you can view the error in event viewer.

Possibly my least favourite AV, and yes, that'll do it.  Glad you sorted it.

Hi Scott-

We upgraded to ArcGIS Server 11.1 and all was fine on ASP.Net 6.0.16. We upgraded the hosting bundle to 6.0.23 and everything was fine. BUT, after upgrading our ASP .NET Hosting bundle to 6.0.26 from 6.0.23 our WA stopped working. We were forced to do this because 6.0.16 had a security vulnerability.

When I uninstalled the web adaptor and was attempting to re-install, I'm got the same error message as in this post (on 6.0.26). According to Microsoft's site, all versions of 6.0## have security vulnerabilities.   

I don't see anything in our event viewer logs-- other than the failure to re-install the web adaptor for not having asp.net hosting, but no more indepth failures.

Do you have any advice on how to track down what is keeping the WA from installing with ASP.NET 6.0.26?

Thanks.

The root cause of your issue is likely unrelated to the issue this thread was opened for, so I suggest you start a new thread since this one was effectively wrapped up 7 months ago.

This was logged as a defect and fixed in 11.2:

Thank you so much for that. I had the .net 6 installed and NOT the hosting bundle. Thanks Scott.
