Solution 1:[1]

I had a similar issue that I solved using this:

Haproxy needs to write to /run/haproxy/admin.sock but it wont create the directory for you. Create the directory /run/haproxy/ first or set stats socket to a different path.

I had the same issue. It turned out the port I had set on the frontend bind was already in use.
