Allocating the resources associated with a FreeFib token will require 10+ minutes. Refresh the page after a while and wait for the actual token to be displayed in the Configuration Parameters ("xxxxxxxxx" in the screenshot). You can add a short title to this hosting subscription to better identify it in case you are using multiple Vifib services. Copy the token. Before going back to the terminal, click on Services in the side menu.
Note, that if you are using this FreeFib token, you must use the the Freefib registry (http://re6stnet.gnet.erp5.cn/). So if you want to use the single line Re6st installer, make sure to use the installer in the gnet/ folder (meaning:
https://deploy.erp5.net/gnet/re6st) when later installing Re6st on a machine with this token (it will have the correct registry URL).
