Issue with Vault Server Upgrade from Helm Chart Version 0.20.0 to 0.28.1 (Vault Version 1.17.2) - TLS Internal Errors Occurring After Upgrade

[chaitanyakoodoo]

Describe the bug

We encountered an issue when upgrading our Vault server using the Helm chart from version 0.20.0 to 0.28.1, which also upgraded Vault to version 1.17.2. After the upgrade, we started receiving the following errors in the Vault server pods:

2024-09-18T10:41:18.669Z [ERROR] core: error during forwarded RPC request: error="rpc error: code = Unavailable desc = connection error: desc = \"transport: Error while dialing: remote error: tls: internal error\""
2024-09-18T10:41:19.244Z [ERROR] core: forward request error: error="error during forwarding RPC request"
2024-09-18T10:41:19.402Z [ERROR] core: error during forwarded RPC request: error="rpc error: code = Unavailable desc = connection error: desc = \"transport: Error while dialing: remote error: tls: internal error\""
2024-09-18T10:41:19.671Z [WARN]  core.cluster-listener: no TLS config found for ALPN: ALPN=["req_fw_sb-act_v1"]

Due to these errors, we had to revert the Helm chart to the older version to restore functionality. We need assistance in resolving this issue so we can proceed with the upgrade.
