Aras 12: Error: Cannot access OAuth Server due to 500 (Internal Server Error)

Hi there,

I see you posted on the other thread about this same issue, but I wanted to leave a comment here for people who find this in the future. Aras Innovator 12.0 has new requirements from Aras Innovator 11.0. Please check Section 2.1.2 of the 12.0 Installation Guide and ensure you have all of the pre-requisite applications installed. 

This particular issue seems to be most commonly associated with missing the ASP.NET Core/.NET Core Runtime and Hosting Bundle version 2.1.8.

I personally think Aras does great job documenting!! (one has to read it)

Yet I seem to have this specific component installed and getting the same error. Any other suggestion what may be the problem?

I needed to update .Net Framework 4.7.2 ASP.Net Core/.NET Core Runtime and Hosting Bundle on our server.  Hope that helps.  

Hello,

I just saw this issue on another machine that also already had the runtime and hosting bundle. The issue with that machine was that it was brand new and a recent Windows update that had .NET 4.8 installed but not .NET 4.7.2. I was able to resolve this issue by installing the .NET 4.7.2 developer pack. 

Could you check if .NET 4.7.2 is installed on the server you're having trouble with? One thing to note is that if .NET 4.8 is already installed, you won't be able to use the Runtime installer from the link above since it will complain that a newer version is already installed. That's why I had to use the developer pack instead.

I installed 12SP4 for the first time and running to the same issue. I have installed dotnet-sdk-2.1.804-win-x64 and NDP472-DevPack-ENU and still can't get past the issue. Is there a solution posted anywhere?

Hi Sgopinath,

Sometimes it is the framework license. Send a request for a new license, but this time use your Wireless LAN adapter Wifi MAC address. This is assuming that you have the right .Net Framework/.Net Core Runtime and Hosting. You can change the license in your InnovatorServerConfig in the root directory then reset IIS. 

Best,
