If you are using a tunnel to browse the site and you are using a different port that what the service actually runs on, this can happen.

Th site checks that the IP and port matches what was requested.

Example:  
The site runs on port 443 ( HTTPS ) and you have setup a tunnel to access the service locally on port 12345. You use your local browser to connect to [https://127.0.0.1:12345](https://127.0.0.1:12345) and the page loads.  
The once you try and access some services, the page fails to load with an Error 403:

> CSRF verification failed

The service is checking that the access was supposed to go to port 443, but sees port 12345.

**Solution**  
Change the tunnel to a Dynamic Socks proxy and use that in your browser  
or  
change the port locally to the same port that the service is actually running on. ( E.g. 443 from the example above. )
