Unable to login - Email or Password incorrect

Navigation Data FMS Data Manager
1

Hello,

I am unable to login to the FMS Data Manager.

I have an error saying my Email or Password is incorrect but it isn’t. I only have one email address and the password is copied from the OTP page provided.

Thanks,

Michael

Hi Ian,

I have tried this. No change unfortunately.

Hi,
I have reset your password. You should receive an email at your registered *@gmail address. Please try again!

Cheers,
Richard

Hi Richard,

I reset my password but continue to have the same issue when trying to login.

I tried again this morning using both my normal password and the OTP and still getting the same error of incorrect email/password so I am still unable to login to the FMS Data Manager.

I have no such issue on any other Navigraph login such as website, Simlink, Simbrief etc

Hi ,

If you can log into FMS Data Manager, in Settings, please Unregister Account, restart and login. Any improvement ?

If no joy,

I suggest a fresh start using exact procedure below:

Please disable any Antivirus and firewall. Uninstall AV if needed.

Use Windows to uninstall FMS Data Manager. Specifically:

  1. Press Start and open Apps & Features.
  2. On the right hand side, open Programs and Features.
  3. Find Navigraph FMS Data Manager in the list, select it, and press the Uninstall button above.

If they exist, delete folders:
c:\ProgramData\Navigraph\FMSClient and c:\Program Files (x86)\Navigraph\FMS Data Manager.

Download and install latest FMS Data Manager

If still an issue,

Please try the following:

  1. close your sim´s
  2. close the FMS Data Manager
  3. go into the folder %ProgramData%\Navigraph\FMSClient
  4. delete the settings.conf file
  5. start the FMS Data Manager
  6. login, let the app re-scan your system

Hi,
It looks like something blocks the connection—either a firewall or your ISP. The application can´t reach the server to verify your account.

"error": "Unable to fetch server address."

Can you connect to any other ISP (possibly via Mobile Hotspot) to check if it´s working? Thank you!

Cheers
Richard

I tried with a hotspot but I am struggling to get an internet connection so login is failing due to no internet.

I checked my firewall settings and it’s allowed on both private and public.

Possible that your ISP blocks the server. Any chance to use a VPN connection?

Cheers,

Yes, let me try with a VPN and report back momentarily.

Frustratingly, no change even with a VPN running.

Good Afternoon,

I was wondering if there is anything else I can try to get this working?

17

As a workaround, try Manual Downloads.

Cheers

Yes I have been doing that in the mean time.
