Nexus Market not loading
When a mirror refuses to open, the first instinct is that the market died or the address is stale. Both are possible. The more common cause is your circuit, and the circuit is yours to fix.

Site can’t be reached, or no route to host
The circuit ended somewhere that cannot reach the onion. Force a new circuit (the onion icon, new circuit) and reload. If it fails twice, paste the second address from the box above. A mirror that opens on one circuit and not another is not broken. It is routed.
Tor is connected, the onion is not
Check that the relay indicator says Connected, not Connecting. If it is connected and the onion still fails, try another mirror, then another circuit, then close Tor Browser entirely and reopen it. In that order. Most of the time it is done by step two.
It loads, but crawls
Slow is the default state of Tor, and an onion through a bad circuit is slower. Do not open a dozen tabs and judge it from the worst one. One tab, one reload, a new circuit. If it stays unusable across all three mirrors and several fresh circuits, the market side is the likely cause, and waiting is the only tool you have.
Is Nexus Market down
Sometimes, yes. Markets go down for maintenance, for traffic, for the occasional longer stretch. This site does not publish uptime numbers or a status light, because it does not run checks against the onions, and a green dot here would be a number without a measurement behind it.
What we can tell you: try all three mirrors first. If none of them open across a few fresh circuits, the market is the problem, not the address.
Your connection blocks Tor
Some workplaces, a few hotel networks and a number of countries interfere with the Tor network. The fix is bridges, which Tor Browser can enable from its settings, or a different connection entirely. If the check page on torproject.org reports that you are not on Tor, then no onion on any site will open for you, and that is worth proving before you blame the market.
It worked yesterday
Then check the list on this page before you do anything else. Mirrors rotate. An address that worked yesterday can be retired today, and a retired address fails exactly like a dead market. If your saved address is not in the box above, it is retired, and the three that are in it are the replacement.
