apt update failing with GPG error

Hi, when I try to use the command on my server

apt update

I get the following errors :

W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://repo.nextdns.io/deb stable InRelease: The following signatures were invalid: EXPKEYSIG 467A7CCC8ACFA0B7 NextDNS <team@nextdns.io>
W: Failed to fetch https://repo.nextdns.io/deb/dists/stable/InRelease  The following signatures were invalid: EXPKEYSIG 467A7CCC8ACFA0B7 NextDNS <team@nextdns.io>
W: Some index files failed to download. They have been ignored, or old ones used instead.

I heard it's about an update of the key, will it be fixed soon ?
