Trying to recover email addresses with correct phone number and name returns "something went wrong" message

Anyone has an idea why would that happen? I have a couple of different Google accounts associated with the same phone number. One of them was opened when I registered to some service and preferred to use a different email address and name.

As things go, I needed to access that Gmail again but forgot the exact address. I eventually recalled it on my own (and also managed to reset the password once I had the correct address), but for some reason Google would not recover my address even though I gave it the correct details.

If I give it the exact full name used for that specific account, after verifying my number it returns that error message. Actually, it does the same even if I try recovering my other addresses (under my real name, with the same phone number).

It used to work fine, so what might have gone wrong now? Thanks.
