WTN Market not working. Or is it?
Before concluding anything about the market, conclude a few things about your setup. Run the list top to bottom.
1. Is it even Tor?
A .onion address won’t open in Chrome, Safari, or Brave under normal settings. If you’re reading an error from a regular browser, you’re done; the address works fine somewhere else. And the “Tor” in a browser extension is a proxy hop, not Tor Browser. Full browser, installed fresh from torproject.org.
2. Circuit trouble
Tor Browser offers a new circuit, sometimes called a new identity; a fresh circuit sometimes reaches a hidden service an old one couldn’t. If your ISP meddles with connections, add a bridge in the browser settings and retry.
3. The address itself
v3 onion addresses are 56 characters, drawn from the alphabet a-z2-7, ending in a checksum-like tail of 14. One wrong character out of 56 loads a different site. Compare the string in your bar against the list at the top of this page, character by character, prefix and tail. The shared prefix is easy to eyeball; tails are where typos hide. Here is why, and here is the paste tool.
4. If none of the three opens
Nothing on a clearnet page can tell you whether the service is down, because a clearnet page knows nothing about it. Your three strings are the whole list, and the right next step depends on what each one says when you try it.
A green dot proves nothing
Plenty of pages print an uptime figure or a status light beside an onion address. Treat those as decoration. A dot on a clearnet page is a claim about a moment that has already passed, made by software you cannot inspect, about a circuit that is not yours. Your own browser, right now, is the only thing that can tell you whether an address answers for you.
