HI @guru

Previouse thread (Invalid signed message generated by @tkey-mpc sdk package js ) regarding eth signer closed automatically everything was fine till today suddenly we got this error without any changes

Precompute failed, error: Some(General(GeneralError { descstring: “read_msg: Session desn1-verifier\u{1c}aganjalip@gmail.com\u{15}default\u{16}0\u{17}3b845ad7d552621a5de850153bae0d4875e7198966ef1c3e6ff5f1b614f8f46f: 3<-0: desn1-verifier\u{1c}aganjalip@gmail.com\u{15}default\u{16}0\u{17}3b845ad7d552621a5de850153bae0d4875e7198966ef1c3e6ff5f1b614f8f46f~chi:208: unknown cause” }))

at this line of sign function:

      client.precompute(tss, {
        signatures,
        server_coeffs: serverCoeffs,
        nonce: scalarBNToBufferSEC1(new BN(0)).toString("base64"),
      });

Hey @aganjalip
the example works fine for me can you try again
if issue persists let us know

also remove nonce variable and try once

if issue persisits let us know
will assist you over a call

the error apears time to time. I will remove nonce and inform you about the result.
