How do I connect my 3DS to a mobile hotspot to obtain old Gen 4 and 5 Mystery Gifts?

Question

I have an Android phone from 2024 and whenever I try to connect my 3ds to it, it will connect for about 15 seconds before kicking itself off. I turned off my security on the mobile hotspot to allow my 3ds to connect. it used to work back in 2023 but I can't figure out for the life of me how to connect it again. any advice would be greatly appreciated!

- Are you able to try again? I updated the DNS in the answer and there has been a Wiimmfi maintenance since you posted.
- 51200 is an unusual error code. If you see that again, what else does it tell you?

it doesn't give error code 51200 anymore but instead it gives me
52101 which says
"Unable to connect to Nintendo Wi-Fi connection. Confirm Connection settings and Access point settings.

and when I do manual setup and input the hotspot name, it gives me 51200 which says the same thing as 52101

Wiimmfi's error code lookup says 521XX indicates DNS failure, which is strange. Not saying I don't believe it but I suspect the issue is with your phone's hotspot generally, especially if other devices can't use the internet from it either.
Some things to try:
- Restart the phone
- Connect the phone to a different network and then re-enable the hotspot
- Delete all three connection setups on the DS and restart the process from the guide
- Try connecting to Mystery Gift even if the connection test fails
- Borrow a friend's phone and see if the same setup on your DS will work with that
