**Description:**  
One of our Percona XtraDB Cluster (PXC) nodes is repeatedly logging Galera-related warnings followed by a crash. The issue starts with multiple “Failed to accept: remote\_endpoint: Transport endpoint is not connected” and “Handshake failed” messages (unsupported protocol, version too low, invalid encoding, internal error), and then MySQL terminates with a signal 6.

**Error snippet:**

```auto
[Galera] Failed to accept: remote_endpoint: Transport endpoint is not connected
[Galera] Handshake failed: unsupported protocol
terminate called after throwing an instance of 'boost::exception_detail::clone_impl...'
what(): remote_endpoint: Transport endpoint is not connected
mysqld got signal 6;

```

**Environment:**

- Percona XtraDB Cluster 8.0.28-19.1

- WSREP version: 26.4.3

- OS: (insert your OS here, e.g., RHEL 8.8)

- Crash occurs during Galera handshake / SST phase.

- Recovery attempt fails with:

**What I’ve tried so far:**

- Verified network connectivity between nodes

- Checked Galera ports and SST donor configuration

- No clear hardware issues observed

**Request:**  
Looking for guidance on possible causes (e.g., protocol mismatch, Galera version incompatibility, or network/socket issues) and recommended diagnostic or recovery steps. Are there some patch which can be applied to overcome this issue?

can you share the my.cnf from the nodes having the issue you have reported.

“2025-10-29T07:42:35.613518+03:00 0 [Warning] [MY-000000] [Galera] Handshake failed: no shared cipher”

This happens when:

1. Different OpenSSL or Galera versions exist between nodes,  
e.g. one node uses OpenSSL 3.x (TLS 1.3 only) and another still uses OpenSSL 1.1.x (TLS 1.2 default).
2. Custom `wsrep_provider_options` explicitly restrict allowed ciphers, or
3. OS-level crypto policies differ.

When that happens, Galera logs “no shared cipher,” then fails the TLS handshake, then `mysqld` crashes with signal 6.

Start by checking that the openssl version is the same on you Nodes.

```auto
openssl version

```

One thing you can try would be to Disable SSL for Galera temporarily (quick test). If you nodes start then you know there is a issue with your SSL on your nodes.

If your cluster doesn’t need encrypted replication inside a trusted network, you can disable Galera SSL to confirm that’s the root cause.

SSL Versions are identical to nodes. This error came when it was going through Security scanning.

Any insight on this would be helpful.

There was similar bug reported which seems to be fixed in 8.0.29. Suggesting you to upgrade to latest 8.0

Did you try disabling Galera SSL to confirm root cause, as I had suggested?
