Describe the bug
All the DKG authorities cannot proceed with signing due to the error Signing protocol concluded with Err(GenericError { reason: "Will skip signing since local key does not exist" }).
Context :
The error appears in the attempt to sign RefreshVote for session 372. The keygen executed without issues for session 372, but on trying to sign the RefreshVote proposal this error appears. All the nodes report the same error so this is likely not a DB corruption issue, something caused all authorities to discard the signing key for session 372.
Env :
All DKG nodes were running at v0.4.1, after the error appeared upgraded to v0.4.5 but the error persists
Goals :
- Restore the signing mechanism and enable session progress
- Find and fix root cause
