How to remove a failed node

Hi, 
i have a multiserver Carbonio 25.3.1 in Ubuntu 22.04 LTS working good

• 1 Proxy + MTA mail1
• 1 MTA mail2
• 1 MESH  mesh
• 1 MAILBOX mailbox

Today we had an electric outage, after that mail2 refuses to bring carbonio services, so i decided to remove this failed node and rebuiild.

Follow this  https://docs.zextras.com/carbonio/html/admincli/administration/removeserver.html#node-removal but we get an error trying to 

export CONSUL_HTTP_TOKEN=$(gpg -qdo - \
/etc/zextras/service-discover/cluster-credentials.tar.gpg | \
tar xOf - consul-acl-secret.json | jq .SecretID -r)

Enter passphrase: What passphrase should i put?

gpg: decryption failed: Bad session key
tar: This does not look like a tar archive
tar: consul-acl-secret.json: Not found in archive
tar: Exiting with failure status due to previous errors

any help will be appreciated.
