I had this problem below:
I have forgotten the password to log-in the Unreal Engine so simply I asked to reset the password. So when I have received the reset code from UE I tried to add a new password (add password + verify password) but then all the problems started as I got the reply "Sorry, the code you are using couldn't be found." Again I thought some problems just simple happens. So I have tried to send a mail answer that I have problem with the page "Reset Password". Then suddenly for my first time I see a message " Delivery Status Notification (Failure) " and I can't find any solution how to contact the support or to send a mail to account-services@epicgames.com in order to solve a simple problem, at least I think a reset of password it is simple. And the biggest issue was that anywhere to ask a question wanted to log in which means to have the missing password or at least haven't found any other place for support.
Please if anyone can help will be appreciated
p.s. I can send mails everywhere else.
The problem is solved as finally I tried the correct password but this isn’t a solution. If anyone knows what one must do in a similar case I believe would help the answer.
