What should I do when I receive a Login failed message when trying to access the Swarm Dissemination Server?

Access to the Swarm Dissemination Server requires an active account in ESA’s EO Sign-In system.

If you have not already registered an account, follow our guide to register an EO Sign-In account.


If you already have an account, but logging in to the Dissemination server fails, please check that you have completed the following steps:


  1. Activate your user account by clicking the link in the confirmation email you received

  2. Check that you are using same email and password you selected when registering your EO Sign-In account

  3. If you are using FTP clients such as Filezilla, WinSCP etc. use “Explicit Encryption” as described in our guide to the Dissemination Server

  4. If you are using command line scripts, check that you are using the LFTP client as described in our guide to the Dissemination Server
