SSRS cannot save/upload report to Report Server

I have a 10mb Report that I am trying to upload to my SQL Report Server. When I would save it, I ran into the maxRequest Length exceeded error. So I edited the web.config file and changed the httpRuntime line to the following:

httpRuntime executionTimeout="9000" maxRequestLength="1048576" requestValidationMode="2.0"

Now I am running into a new error. Whenever I try to save my report from report builder or upload through the SSRS GUI, I now run into this error:

--Client found response content type of '', but expected 'text/xml'. The request failed with an empty response.

--The attempt to connect to the report server failed. Check your connection information and that the report server is a compatible version.

I am not sure why I am running into this error. The server is running fine and I can run my other reports, just not save this one to the server.

EDIT: Here is an error I am finding in my logfiles when trying to save the report:
