Login for access to HPC or Mars fails

These services are available to authorised users only. Please see conditions of access for further details.

Login to VDI fails

While everywhere else on your PC, the local keyboard layout applies — within VDI it does not.

If you are using some special characters in your password, these might be located differently on the keyboard, depending on the keyboard layout. Sometimes even the normal letters are different (qwerty / qwertz / azerty). 

Please check the VDI's own keyboard layout (in the upper-right corner of the screen), and choose the one that fits best your hardware keyboard. (For Qwerty EN1 or EN2 for MAC)

Once you are logged in, you may go to the keyboard settings and remove the unnecessary ones from the list.


Login to other services fails

If the initial login works via the ECMWF website but fails on any other service, please raise a ticket
