Need help with Lync Edge Servers

Which version of the doc did you use. I remember one of the early ones I used it didnt work. I figured out by removing the SSl profiles it worked. The new version of the doc has fixed it. It looks like you have a SSL client profile so you may have just used an older version of doc. Set it to none and it should work. BTW, you are using Source Address Affinity for persistence method, correct?
