seems to be a slight different approach. I have haproxy on one VM (where https is exposed) and all other services (like nextcloud, ...) each on one VM.
My approach till now looks so (parts of my haproxy.cfg):
`frontend www-https
bind *:443 ssl crt /etc/ssl/combined.pem alpn h2
acl is_grommunio path /web
use_backend grommunio if is_grommunio
backend grommunio
server gromox grommunio:80 check`
Of course for ActiveSync that is not enought but step by step.
But: with that simple approach (which worked with kopano) I only get 301 errors...
Has somebody an idea why?
Thanks and Kind Regards
