Yes, uwsgi and nginx is runnning
roundcube access successfully.
only iredadmin, Pro or not,
you can have a clean installation without doing anythings, and you will end up in this. as i have try many times.

Re: a newly install iredadmin got 502 bad gateway error

Does your server have file /run/uwsgi/iredadmin.socket when uwsgi service is running?

How about try out cloud-based iRedMail installer instead?

Is the last ':' a typo error? Could you show me full content of file /etc/nginx/templates/iredadmin.tmpl?

Re: a newly install iredadmin got 502 bad gateway error

SOLVED!! by
yum -y install uwsgi-plugin-python2
service uwsgi restart
but i found out i did many things
some other sample after fresh installing using the command above result in Internal Server Error.

Thanks for sharing. EPEL changed the package name few months ago.
