I can reproduce this. We’ll be doing a 2.5.1 build to address this issue. I’ve added this to the Known Issues on the release notes.

zalcorshark · November 9, 2021, 3:10pm

Can also confirm this issue. I was able to do the following to fix this issue in our environment:

Pre-Upgrade Settings:

IIS Windows Authorization: Disabled
appsettings.json : Windows Authorization: false

Post-Upgrade Fix:

CHANGE IIS Windows Authorization: Enabled
No change to appsettings.json. Kept Windows Authorization False

I’m using OIDC integrated with Azure for connecting to PSU.

We have a fix for this and have released a nightly build (1440520023): https://imsreleases.z19.web.core.windows.net/

Doing some more testing and then we’ll get this out later today or tomorrow.

wsl2001 · November 9, 2021, 7:39pm

issue still remains the same after testing above nightly.

adam · November 9, 2021, 7:59pm

Just pulled and installed the nightly via the ZIP and it’s working for me so let’s figure out what’s different here.

https://imsreleases.blob.core.windows.net/universal-nightly/1440520023/Universal.win7-x64.2.5.1.zip

I unzipped to C:\inetpub\wwwroot\PowerShellUniversal and ran Unblock-File.

Test 1 - Windows Auth

web.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />
    </handlers>
    <aspNetCore processPath=".\Universal.Server.exe" arguments="" forwardWindowsAuthToken="true" stdoutLogEnabled="true" stdoutLogFile=".\logs\log" hostingModel="OutOfProcess" />
  </system.webServer>
</configuration>
<!--ProjectGuid: 588ACF2E-9AE5-4DF1-BC42-BCE16A4C4EDE-->

appsettings.json

  "Authentication": {
    "Windows": {
      "Enabled": "true"
    },

Success

Test 2 - Form Auth

web.config

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <system.webServer>
    <handlers>
      <add name="aspNetCore" path="*" verb="*" modules="AspNetCoreModuleV2" resourceType="Unspecified" />

  </system.webServer>
</configuration>
<!--ProjectGuid: 588ACF2E-9AE5-4DF1-BC42-BCE16A4C4EDE-->

appsettings.json

  "Authentication": {
    "Windows": {
      "Enabled": "false"
    },

Success

I have done exactly the same and verified all above and same exact issue

am using windows server 2019 & 2022 and same issue.

going back to ver. 2.4.1 everything works again.

wsl2001 · November 9, 2021, 9:10pm

Update: when i change the port for the site from port 80 to port 82 it works but still error if am using port 80.

adam · November 9, 2021, 9:13pm

Weird…80 works fine for me. Do you have multiple sites on the same IIS machine?

wsl2001 · November 9, 2021, 9:14pm

i have just 1 site and the default web site

adam · November 9, 2021, 9:15pm

Ok. I’m standing up a brand new Server 2022 instance to try there.

wsl2001 · November 9, 2021, 9:15pm

Update: i switch the port back to 80 and now its working

wsl2001 · November 9, 2021, 9:16pm

It looks like because of the issue you need to change the port and change it back. so weird

adam · November 9, 2021, 9:24pm

That is weird. Glad it’s working now.
