Downloaded FMS Manager on both MacOs and windows, tried to login using Navigraph credentials and one time password.
I queried ChatGPT and it said this:
“The version number 1.8.14 shown in your log confirms you are running an outdated build of the Navigraph FMS Data Manager. The authentication failure (grant_type=password) happens because Navigraph updated their security servers to reject direct password inputs from older client builds.”
Attached is a log file

The log would suggest that your credentials are incorrect so make absolutely sure that your username and password are correctly entered. If you are unsure, I would recommend creating a new password.
Also, if you are using any antivirus or VPN, disable these for the meantime as you test the sign-in process.
I have tried many combinations of credentials as well as changing my password. I also saw a topic about the same problem on your support site. I also follwed the suggestions and turned off the firewall and anti virus but no luck.
It appears that the other person had no resolution other than manually download the data. I did that and was able to successfully get the data installed. I would be nice if someone took a look at the app to see what’s going on. I can try again and attach the log (which I did in original post) if that would be any help. If there is a beta version of an update perhaps I could try that?
The issue’s root issue was that when you deleted your account, for some reason our database never updated, keeping the old accounts credentials stored. The issue was compounded since the deleted account and your new account have exactly the same email address.
Thats completely on us, though, and we have an internal ticket to investigate exactly why this happened.
Can you completely close FMSDM, then start it and try to sign in again.
Ok I was able to login
thanks for the quick response!
Ok now I can’t add any add on mappings.
FMS Manager found my X-Plane directory, and I have a FlightFactor 777 airplane and little navmap
I can’t add those or anything else
The scan did not find anything
Never mind, I uninstalled FMS manager and reinstalled, and it found my addons
Great to hear that! I’m glad the issue is resolved!
