I had the same problem whilst doing a round of updates.

Go to Window > preferences

go to install/update > Available software sites

scroll with the bottom scrollbar to the right so the location urls are in view and locate the tm4e url.
Select it and click the edit button.

Add a slash at the end of the url.

Hit apply and close and now check for updates.

You need to make sure that you have unchecked 'Contact all update sites during install to find required software'.
