I am trying to upgrade vault to 1.6.5. my current version is 1.5.6. I have three node HA configurations using raft.
- Node - 1 - upgrade to 1.6.5
- vault unseal done
- vault operator raft join ( this is failing with following error):
Error joining the node to the Raft cluster: Error making API request.
Code: 500. Errors:
- failed to join raft cluster: failed to join any raft leader node
When I revert the vault version to 1.5.6 this is not issue and things works fine. any pointers would be help here. we are facing this issue to upgrade to 1.6.5
