SSL errors with HAProxy (1 reply)

i am not sure what i am doing wrong, but i keep getting errors in my
browser when trying to browse to my site. i just moved from an old OS
and HAProxy instance to current, and may have issues with config
directives to work out. please be patient :)

just about every third request works. otherwise i get "Error code:
ssl_error_rx_record_too_long" errors in firefox. if i try to reload the
page, it takes a couple tries, but does finally load. i have no idea
how the error exists for some of the requests but not for all. relevant
info below. any help is appreciated. any other info needed available
upon request:
