Summary

Every provider's self-host doc lists the Docker OAuth2 redirect URI as http://localhost:5000/integrations/social/<provider>, but the official postiz-docker-compose setup (the one linked from the Quick Start) maps the app container to host port 4007, not 5000:

MAIN_URL: 'http://localhost:4007'
FRONTEND_URL: 'http://localhost:4007'
ports:
  - "4007:5000"

Port 5000 is only the container's internal port. A browser following the standard Quick Start setup can't reach localhost:5000 directly, so every provider's documented Docker redirect URI is unreachable as written, and registering the redirect URI exactly as documented fails during the OAuth callback.

Found this firsthand while self-hosting Postiz locally via postiz-docker-compose and registering a LinkedIn developer app for OAuth.

Changes

Updated the Docker: redirect URI line in all 17 affected provider docs (18 occurrences, Instagram has two) from localhost:5000 to localhost:4007, matching the official compose file. tumblr.mdx already had the correct port and was left untouched.

Test plan

• Confirmed the actual port mapping in postiz-docker-compose's docker-compose.yaml ("4007:5000", FRONTEND_URL: 'http://localhost:4007')
• Reproduced the mismatch live: self-hosted the stack, registered a LinkedIn app with the documented localhost:5000 URI, confirmed localhost:5000 isn't reachable from the host/browser
• grep-verified no remaining localhost:5000 references across self-host/providers/
