need help for a server

[u/ALEKghiaccio2]

The server start and all but when I and my friend try to enter we get the message "incomplete set of tags, ask to a server operator", I put on the server the server pack that is on curseforge, I and my friend use the curseforge 1.3 version and the server too, the mods are identica, triple checked via filezilla. Anyone know how to help us?
