The reason for the set is that we have other if statements and rewrites but they shouldn't be conflicting because they're the same as on other subdomains we use. I commented it all out just in case to test this.

In there error logs I get /home//martin.dev.testsite.com which means that $myhost is empty so the regex isn't returning anything.

We're changing our format to branch.martin.dev.testsite.com to be more valid. I'm reworking the regex like so:
^\.*(.+)\.dev\.testsite\.com.*$

But it's not done yet clearly. In my regex tester that returns the name I want but nginx doesn't seem to do it.
