relates to
I am having this same issue for my custom domain. I get an "IllegalArgumentException: Registration failed." when attempting to register under an @oru.edu address.
@TheL0of Imagine wanting to make a sniper without even being able to pass registration. LOL
I want to register 25 new accounts with email addresses like yx01@mydomain.ch
- xy25@mydomain.ch
I could register one email, for the other ones I got this error message:
We want to start a Minecraft Challenge at work and would appreciate if this could be fixed ASAP.
See WEB-1647
Please consider reopening this issue, [Mod] Greymagic27. This is not a duplicate of WEB-1647.
Multiple users has reported this bug under that ticket in just a few days, thus we can say that this is a new bug which occurred recently.
As commented in WEB-1647: I was able to create an account using my own domain. Issue is solved for me.
I can confirm it to - I was able to create an Mojang account in MC website with using my own domain and buy a copy of the game. Thank you. May I ask, what was wrong/broken ?
IMHO: I thing that Moderator of this bug tracker should add error message ( "IllegalArgumentException: Registration failed" when trying to register a new account ) in title of this bug - when Google index this thread users go here and redirected to closed thread to WEB-1647 where just right now someone add a comment probably without reading all comments ![]()
Edit: I confirm that What is just commented in WEB-1647 by Yves Peissard - now when i want to create second account with the same my own domain, that i just recently create account and buy a copy, that now i was not able to do that with the same bug appears "IllegalArgumentException: Registration failed".

Are you using any sort of VPN?
Same here, and I don't use a VPN.
Confirmed, I can't seem to register an new account at this time. I'm using my own email service and before I was able to get one last year
Same here
We are seeing registrations all the time, so there is no general problem with registrations. So please contact support with your details about the issues you are seeing to get help registering: https://help.minecraft.net/hc/en-us/requests/new
Same here,
I do not use any kind of VPN, I send request via form from link above without any response (except auto responder). I'm try few domains belongs to me without any luck. May We known what's going on ?!? Is some black lists domains / IPs or something? No one before try too use my domains for creating minecraft/mojang accounts. As you can see I'm able to create account here (help.mojang.com) with the same email address... That's sucks
I have my own domain and using this domain I'm able to create an account for Jira (this ticket system) but not for the Minecraft website.
When trying to buy the Java edition of Minecraft via https://my.minecraft.net/nl-nl/store/minecraft/#register, I constantly get the error " IllegalArgumentException: Registration failed."
This means I'm not able to buy the game. Opening a ticket at Minecraft wil not work either because I don't have an account.
Can you tell me how can I buy the game?
FYI: I'm also not using any kind of VPN and I can share my domain name in a personal message.
Mr Robert Robert Sjödahl can you explain us what is going on ?!? as reported identical bug
WEB-2322has invaild status...Mojang Support is not responding
provided from link above https://help.minecraft.net/hc/en-us/requests/new is without response form them 
and second thing:
I''ll make a simple test - i just create a new account at GMail service and used that newly created email address to create Mojang account with success. Then, I'll to create Mojang account with email address with one of my own domain with reported bug - "IllegalArgumentException: Registration failed"...
May we known, why registration in Mojang/Minecraft is filtered by mail / host provider ?!?
If you're still having the issue see
WEB-2306Yes, the problem still exists. I'll be watching the
WEB-2306thread.I was able to create an account using my own domain. Issue is solved for me.
