I had a similar issue. I resolved it by changing

<basicHttpBinding>

to

<basicHttpsBinding>

and also changed my URL to use https:// instead of http://.

Also in <endpoint> node, change

binding="basicHttpBinding" 

to

binding="basicHttpsBinding"

This worked.

I solved this problem by setting UseCookies in web.config.

  <system.web>
    <sessionState cookieless="UseCookies" />

and setting enableVersionHeader

  <system.web>
    <httpRuntime targetFramework="4.5.1" enableVersionHeader="false" executionTimeout="1200" shutdownTimeout="1200" maxRequestLength="103424" />

Even if you don't use network proxy, turning 'Automatically detect settings' in proxy dialog makes this exception go off.

Answer 4

My solution was rather simple: backup everything from the application, uninstall it, delete everything from the remaining folders (but not the folders so I won't have to grant the same permissions again) then copy back the files from the backup.

As with many, in my situation I was also getting this because of an error. And sadly I could just read the CSS of the html error page.

The source of my problem was also a rewrite rule on the server. It was rewriting http to https.

I tried all the suggestions above, but what worked in the end was changing the Application Pool managed pipeline from Integrated mode to Classic mode.
It runs in its own application pool - but it was the first .NET 4.0 service - all other servicves are on .NET 2.0 using Integrated pipeline mode. Its just a standard WCF service using is https - but on Server 2008 (not R2) - using IIS 7 (not 7.5) .
