Please confirm you are trying to update MSFS and/or MSFS addons.
Have you been able to sign in to Navigraph Navdata Center (NNC) at any time?
Please confirm you are trying to log into NNC v 1.0.10.
I managed to log in several times, but two weeks ago I did not enter the application, but when I came two days ago to open the application this is what happened
Finally, I knew what the problem was.
I went to communitya file and I deleted all files related to navdata and AIRAC Cycle
Then I deleted the application and downloaded it again and logged in and the method succeeded.
. Thank you so much @Ian for trying to help me
