What it means
Access is denied because of a legal demand. Client errors mean the request cannot be fulfilled as sent. The server is working, but the address, permission or request rate is the problem.
Common causes
Court orders, censorship or regional legal restrictions.
How to fix it
Nothing to fix technically; contact the site owner.
If you are a visitor
Check the address for typos, sign in if the page needs it, and try again. If you believe the page should exist, tell the site owner.
If you own the site
Retrying the same request will not help until you change something (URL, credentials or timing). URLs that keep returning 404 or 410 are dropped from search results over time. 429 and 403 can block crawlers if they are too aggressive or blocked by a firewall. Run the HTTP status checker to see exactly what your URL returns, and use uptime monitoring to be told when it changes.
