HTTPS ERROR 500 appears when entering SAS Studio

[mendim02]

Hello,

When SAS loads normally, and I get to the localhost page, I click "start studio" and this error message appears (see below). 

Is this an error on my end, or is the server down? I am using the most up to date version of SAS University, on my Mac Book, and using Oracle VM Virtual Box Manager. I tried restarting my computer twice, but still get the same error.

Please let me know at your earliest, thank you very much.

Hi @mendim02 ,

Here are a couple earlier discussions about this error that might be helpful - try deleting the SAS University Edition instance within VirtualBox and reimporting it. If that doesn't work, you might need to try re-downloading SAS University Edition.

HTTP Status 500 - java.lang.ClassFormatError: Truncated class file

Unable to connect with SAS University Edition

I hope that helps!

So this is what I did.

I am assuming you are running Catalina OS Beta.

Uninstall VB, and reinstall it.

Reinstall the application .ova

Set up the folders the same way etc.

Run the virtual machine as "Detached Start"

Before exiting the machine, make sure to "Save the state" of the machine. Do not SHUTDOWN the virtual machine. If you do this, you will have to repeat all the previous steps.

Lastly, do not use SAFARI. You will not be able to upload files. Use Firefox.

Hi,

Step 1:

Remove the unvbasicvapp (sas file) from VM ware work station.

Reimport the file once again into VM ware workstation.

Step 2:

Remove the cache from the browser and then run the sas app in the VM ware workstation.

Step 3:

Now open the address http://192.168.124.129 in the browser as mentioned in the VM Ware work station.
