I am not receiving the email from the "forgot my password option"

I am talking about another account, not this one.

Context first. One year ago I changed my email on reddit.
Let's say I changed from email A to email B. When I did it, I received an email on my email A saying "from now on your reddit profile is linked to email B". And I can see this email up to today and there is no typo or anything wrong with email B.

Back to today now. I dont remember my password. So I clicked on forgot my password, typed my email ( email B, which I know for sure that is the one linked to my account, since I have an email on email A showing that ), but I never receive the actual email from reddit with a link for changing my password. What can have happened? I really dont wanna lose my account.
