I use nginx proxies to connect subdomains to various docker services. Since one of the latest image updates, I can no longer connect to my gitlab instance. I don't know if the nginx-proxy or gitlab update caused this problem. When I try to connect to gitlab.mydomain.com, I get the following errors:
- Browser: 502 Bad Gateway. Nginx / 1.13.3
Nginx-proxy logs:

My file is the file for the dock:
version: '2' services: nginx-proxy: image: jwilder/nginx-proxy ports: - "80:80" - "443:443" volumes: - /var/local/nginx/certs:/etc/nginx/certs - /etc/letsencrypt:/etc/letsencrypt - /var/run/docker.sock:/tmp/docker.sock:ro gitlab: image: gitlab/gitlab-ce:latest ports: - "2222:22" hostname: 'gitlab.***.com' expose: - 443 - 22 - 80 - 25 environment: - "VIRTUAL_HOST=gitlab.***.com,www.gitlab.***.com" - "VIRTUAL_PORT=443" - "VIRTUAL_PROTO=https" volumes: - "gitlab-config:/etc/gitlab" - "gitlab-log:/var/log/gitlab" - "gitlab-data:/var/opt/gitlab" - "/etc/letsencrypt:/etc/letsencrypt"
Any ideas on this? Thanks.
