HTTP Status 500 - Cannot call sendError() after the response has been committed
Asked by Jason Garland:

Fresh Windows 2016 x64 Installation w/ SQL 2014 Std

After Installation (No Errors Reported), I connect to the WebPage and insert my license code. After this, I receive the following and cannot move on.

Windows Firewall has been disabled, and removal and reinstallation of Confluence has been done. I have checked the knowledge base and cannot find a reference to this error.

author: Shannon S
body: Hello Jason,

Do you happen to be behind a proxy as well? If so, could you try to [bypass the proxy](https://confluence.atlassian.com/confkb/how-do-i-bypass-a-proxy-to-test-network-connectivity-402031184.html) and let us know if you still see the error?

It will also help if you can tail your [Confluence Server Logs](https://confluence.atlassian.com/doc/working-with-confluence-logs-108364721.html) when you encounter the error and let us know if there are any further details, such as a "caused by" line. The error you see can be the result of many issues, so if we can get more specific messages in the logs, it will help narrow down the issue for us.

Regards,

Shannon
