# All Domains show Nginx 502 error This happens when a third party user/service restarted docker and the floatingip service failed to reload the `/etc/hosts` file with new docker private IP addresses. To resolve this issue, run: ```bash opencli server-recreate_hosts ``` Then restart Nginx service: - soft restart (reload without downtime): ```bash docker exec nginx bash -c "nginx -t && nginx -s reload" ``` - hard restart (stop and start again): ```bash docker restart nginx ```
