HTTP Status 500 - Cannot call sendError() after the response has been committed

[Jared Butler]

After setting up the database and getting Confluence installed, I can make a successful connection to the database but after clicking NEXT and waiting for setup to continue, I receive the following 500 server error.  I am using MSSQL 2017 Standard.  I've followed all of the guides on here and am on my 5th or 6th attempt at installing but cannot get past this error.

Shannon,

I was able to get it to install after several tries, and I'm not sure exactly what finally worked.

I did follow the guide that you referenced and the firewall was off.  It was something with my database/permissions.

Thanks,
Jared

Hi Jared,

Thank you for letting us know! Glad you were able to get it installed.

Take care, and have a pleasant week.

Regards,

Shannon

Jared,

I just want to confirm that your MS SQL setup was done using this guide; can you confirm?

Can you let us know which method you used to install Confluence? Can you confirm if any proxy or firewall is involved?

Usually this error is a symptom of another problem, so it will help if you can check your Confluence server logs to see what error message is being served with the 500 error? 

Regards,

Shannon
