By not accessible you mean you are not able to open the link?

I never was able to fix this, and still have this problem in the latest version. Is there anything I haven't tried?

Do you have access to a wired internet connection (Ethernet)?
According to Wifall's tutorial here, in the P.S. part, using Direct Mode could help.
Otherwise, maybe trying to connect using different Wireless access points, maybe a different ISP...

Unfortunately I don't, and for ISPs and access points I don't think it's worth the hassle.
Guess I'm all out of options, then?

Try installing the Microsoft Loopback Adapter and use the direct mode with it.

did you try to use the same ROM as your friend? (both using pokémon Black for example). did you manage to find any solution? I have the same problem.

Adding onto this thread after a over a year (lol), since I've been trying again

I've been using Kaeru WFC (178.62.43.212) and followed the most recent guide

HeartGold and SoulSilver work. Sometimes one player can't see another in the Wi-Fi Club, but disconnecting and rejoining fixes it.

The gen 5 games (B/W and B2/W2) still mostly do not work. GTS seems functional, but that's it. I'm not getting error 86420 in the Wi-Fi Club anymore, just getting a completely endless loop, never getting a failed to respond message or anything like that. Only ends when one side forces a communication error (pausing, resetting, quitting, fast forwarding for a while, stuff like that).

I've tried everything I talked about before. Never changes. Haven't tried loopback adapter, but I'd rather not have to go through direct mode, as that isn't really a viable solution for playing with my friends.

Both the error 86420 and the endless loop are probably related to ports blocked either by the ISP or the Router, it can be either due to your router or your friend's. I recommend trying phone data hotspot to see if it works.

As I've previously mentioned in this thread we have already tried with phone hotspots. Doesn't change anything. I also have tried with a few different friends, and they have tried with one another as well. All of us get the same issue every time, just the endless loop of waiting for a response.

HG/SS works fine though, for all of us.

HG/SS working while B/W(2) don't is a strange issue, it almost seems like it's blocked ports somehow. It's hard to pinpoint the issue since it can be either at your side of connection or your friend's. Try following the Extra Step described in this tutorial here to reset your friend codes, this can solve the issue if it's server-related.

I did have all of my friends (and myself) erase WFC configurations before attempting already. And I'll add that my friends can also connect with each other in HG/SS and fail to in B/W, so it doesn't seem to be something specifically on my end.

I see. Well, if you want, you can hop in melonDS Discord so we can troubleshoot it together later. Here's the link https://discord.gg/RrH4bNQQMz

Okay, I've joined the discord.

Going to add one more thing to this thread though: Platinum also works, so all gen 4 games work fine but all gen 5 games loop endlessly in the union room
