Upgrade Path from 1.0.0-alpha.78 to 1.0.0-beta.11-preview.1 [RPC signature verification failed]

[kaiszy]

Hi,

i try to upgrade from 1.0.0-alpha.78 to 1.0.0-beta.11-preview.1 but get the error:

{"timestamp":"2026-07-28T14:17:02.75526872+02:00","level":"ERROR","message":"RPC signature verification failed","event":"rpc_signature_verification_failed","component":"server","subsystem":"http","error":"Missing signature header","target":"rustfs::server::http","filename":"rustfs/src/server/http.rs","line_number":1887,"threadName":"rustfs-worker","threadId":"ThreadId(7)"}

On all nodes the envvar RUSTFS_RPC_SECRET is set to the same value

RUSTFS_RPC_SECRET=ak***fQ

Thanks for your help :)

Best regards,
Kai.

Because it seems to be another Problem as in issue 4967 i reopen this. I do the following:

# set -a
# source /etc/default/rustfs
# set +a
# env | awk -F= '
/^RUSTFS_(ACCESS_KEY|SECRET_KEY|RPC_SECRET)=/ {
print $1 ": configured, length=" length($2)
}
'
RUSTFS_SECRET_KEY: configured, length=64
RUSTFS_ACCESS_KEY: configured, length=64
RUSTFS_RPC_SECRET: configured, length=64

# rustfs $RUSTFS_VOLUMES
