WinSyslog Event ID 11055: Network and TLS transport: TLS operation warning#

Answer#

Network and TLS transport: TLS operation warning. The product recorded this while processing network and tls transport; the appended event detail identifies the affected object, operation, or provider error.

Event details#

Event ID: 11055
Severity: Warning
Component: Network and TLS transport
Windows Event Log source: AdisconWinSyslog
Available since: 26.07
Message pattern: Cwinsock initopensslserversession. Additional detail: {event_detail}

Possible causes#

The destination or listener is unavailable, blocked, bound to another address or port, or configured for a different transport.
TLS certificates, peer authorization, protocol settings, or sender and receiver configuration do not match.

Immediate checks#

Record the endpoint, address family, port, transport, TLS mode, and complete runtime detail.
Verify DNS, route, listener ownership, firewall policy, and TCP or UDP reachability as applicable.
Send one unique test message and verify positive receipt and queue recovery.

Detailed procedures#

Resolve a destination and test its TCP port — Verify DNS, selected address, routing, and TCP establishment.
Verify TLS certificates, private keys, and permitted peers — Check validity, trust chain, key pairing, protocol mode, and peer authorization.
Collect an Event ID and neighboring product events — Preserve the complete event and the product events immediately before and after it.
Export configuration and collect a bounded debug log — Create a text configuration export and time-bounded debug capture, then disable debugging.

Verify the result#

Repeat or monitor the affected operation and confirm that Event ID 11055 does not recur and that network and tls transport processing continues.

Evidence to collect#

The complete Windows Application Event Log entry, including all event detail.
The product name, exact version, service account, and event timestamp with time zone.
A configuration export and debug log covering the same time window, with secrets removed.

Escalation#

If the event continues after the detailed procedures, collect the listed evidence and contact Adiscon Support.
