Products

• VMware VeloCloud SD-WAN

Issue/Introduction

The communication between the Edge and VCO is broken due to an `SSLEOFError`. This error only affects management plane communication, with no impact on the data plane.

SSLEOF error occurs in below scenarios,

The SSLEOFError occurs when an SSL/TLS connection is unexpectedly closed. Here are some common causes:

1. Network Issues: Interruptions or instability in the network path between the client and server.
2. Firewall or Proxy Interference: A firewall or proxy that performs SSL decryption or modifies SSL/TLS traffic.
3. Server-Side Problems: The server might be abruptly closing the connection due to issues like high load, configuration errors, or crashes.
4. Client-Side Issues: Problems with the client, such as SSL/TLS misconfiguration or outdated libraries.
5. Certificate Issues: Problems with SSL/TLS certificates, such as being expired, mismatched, or untrusted.
6. NTP or time mismatch can also cause these SSL errors

Environment

ALL Velocloud SD-WAN edge versions

Resolution

This generally occurs if there is a firewall/proxy server in the middle or network path loss.

If neither of the above issues is the cause, please reach out to support.
