502 bad gateway: Error

[Janis K]

I followed the "deploying" instructions of the documentation: the only difference is that i run a "landingpage" on nginx, because of other web-applications like owncloud that should also run on nginx.

Owncloud (https://localhost/owncloud) runs with my configuration, but if I want to access the https://localhost/mayan i get this:

2016/05/10 15:11:37 [crit] 491#491 *21 connect() to unix:/usr/share/mayan-edms/uwsgi.sock failed (13: Permission denied) while connecting to upstream, client: 127.0.0.1, server: localhost, request: "GET /mayan/ HTTP/1.1", upstream: "uwsgi://unix:/usr/share/mayan-edms/uwsgi.sock:", host: "localhost", referrer: "http://localhost/mayan/"

do you have any suggestions regarding this?

the  /etc/nginx/conf.d/default.conf looks as follows:

Same problem here. Did you fix this and if so, dDo you still know how you managed to?
