0x801901f4 login problem

Hello Carlos,

Thanks for reaching out to us! We apologize for any inconvenience the issue when trying to sign in has caused.
Please go to the Account website and
make sure you are able to sign in. Once you make sure you are able to sign in with the account, perform a
soft factory reset.
It sounds as if the software somewhere is corrupted on the console. Once you do the soft factory reset, try to install your profile again then let us know how it goes.

Side Note:
It is
very important to make sure you know the primary email/password to the account before removing
it from the console.

To check the email being used with the gamertag, go to
Settings > Account > sign-in, security & passkey;
in middle column at the top it will say "show on home"
if it is checked it will rotate from gamertag and email on homepage. If it is not check marked, it will show in this box.

I hope this helps

Hello, do you already performed a console power cycle? this will fix most of the times this kind of issues, here are the instructions in the following link:

https://support.xbox.com/en-US/xbox-one/console/power-cycle-console

Let us know if these sugestions fix your issue, or if you need more assistance?

On other posts that was the solution, did you tried?

Ive read somewhere that you need to delete the account and then re sign in. Is there a problem with that? As in keeping your purchased skins/items?

many thanks
