Why is my site showing multiple broken links in tools when they are all working?

Question

We have built a new site warmseal.westserve.co.uk. When we run it through broken link checker tools it is showing that we have multiple broken links which in reality work.

For example the following link in the top-wrapper is showing as a broken link:

<a href="/callback/" id="call-back" class="left"><img src="/templates/images/phone.png" class="icon" />Request a call back<img class="arrow" src="/templates/images/arrow-right.png"/></a>

Any ideas why some links are showing as broken links?

What actions are needed to stop them showing as broken links?

There is also an issue with XML sitemap tools not picking up all of the pages. I think this is related and by solving the broken links issue it will solve the other.

I have tried making all pages on the site have a trailing / on the end as somebody suggested this may help but this makes no difference and still doesn't work.

Testing http://warmseal.westserve.co.uk/callback/ (using postman) shows that your server is responding with a 404 Not Found status code with an HTML document (that appears to be the desired page) as the human readable error message.
