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!

Not really a Pokemon question but I think we should keep this. Couple points:
- What model is the phone and what version of Android? Any patch level or UI version info from the "about" page in settings may also be relevant.
- What error does the 3DS give you?
- Does the hotspot connection work on other devices?
- How many times did you try again? I sometimes see the first connection test dies but the second works.

-the model is Moto G play (2024) and the patch level is Android 14 the latest update being from July 1st 2025
-the 3DS shoots me the Error code 51200 after connecting for about 15 seconds.
-the hotspot connection doesn't really work on other devices. I wonder if that's it.
-I try at least 1-3 times when I set a new DNS

Also, what guide are you using to set it up and which game is it?

I'm using the guide you posted a while ago and my knowledge of how it used to work. https://pokemondb.net/pokebase/383345/how-to-obtain-all-the-gen-4-5-mystery-gifts?show=383345#q383345
