OCPP-F02Cross-brand / Protocol · DC Fast ChargersFree sampleHeartbeat timeout to CSMS
Heartbeat timeout to CSMS — station may look Available locally while Cloud shows offline, sessions fail Authorize, or Heartbeat gaps appear in the CSMS timeline. protocol field note: keep evidence scrubbed and prove the ranked cause before module RMA on OCPP-F02.
NET-C01Cross-brand / Protocol · DC Fast ChargersFree sampleDNS resolution failure to CSMS
DNS resolution failure to CSMS — charger cannot resolve the CSMS hostname; Soft-offline with local Ready possible. protocol field note: keep evidence scrubbed and prove the ranked cause before module RMA on NET-C01.
NET-C02Cross-brand / Protocol · DC Fast ChargersFree sampleTLS handshake fail to CSMS
TLS handshake fail to CSMS — DNS works but TLS fails (cert/clock/SNI), leaving OCPP down. protocol field note: keep evidence scrubbed and prove the ranked cause before module RMA on NET-C02.
NET-C03Cross-brand / Protocol · DC Fast ChargersFree sampleNAT keepalive drops OCPP websocket
NAT keepalive drops OCPP websocket — sessions work briefly after reboot then Soft-offline until the next reconnect. protocol field note: keep evidence scrubbed and prove the ranked cause before module RMA on NET-C03.
NET-C04Cross-brand / Protocol · DC Fast ChargersFree sampleProxy MITM breaks certificate pin
Proxy MITM breaks certificate pin — corporate proxy intercepts HTTPS and the charger rejects the substituted certificate. protocol field note: keep evidence scrubbed and prove the ranked cause before module RMA on NET-C04.
LOAD-02Cross-brand / Protocol · Power cabinet / LMSFree sampleLMS heartbeat lost — failsafe curtail
LMS heartbeat lost — failsafe curtail — chargers derate or go Unavailable when site LMS/PLC heartbeat drops, protecting the feeder. protocol field note: keep evidence scrubbed and prove the ranked cause before module RMA on LOAD-02.
CLK-01Cross-brand / Protocol · DC Fast Chargers solo+Clock skew breaks TLS / auth tokens
Clock skew breaks TLS / auth tokens — station time wrong enough that certificates or token windows fail, producing Soft-…
CCS-H09Cross-brand / Protocol · Cables & connectorsFree sampleSECC discovery wrong IP
SECC discovery wrong IP — vehicle cannot find SECC on the expected link-local/IP path; handshake dies at discovery/SDP. protocol field note: keep evidence scrubbed and prove the ranked cause before module RMA on CCS-H09.
NET-C05Cross-brand / Protocol · DC Fast ChargersFree sampleMTU black hole on cellular path
MTU black hole on cellular path — large OCPP frames fail while tiny pings seem fine; Boot/FW/MeterValues flake on LTE. protocol field note: keep evidence scrubbed and prove the ranked cause before module RMA on NET-C05.
NET-C06Cross-brand / Protocol · DC Fast ChargersFree sampleCSMS rate-limits StatusNotification
CSMS rate-limits StatusNotification — after a reconnect storm the CSMS throttles, chargers appear offline/Faulted in UI despite healthy hardware. protocol field note: keep evidence scrubbed and prove the ranked cause before module RMA on NET-C06.
ABB-T184-COMABB · Terra 184 · DC Fast Chargers solo+OCPP disconnect after peak
Terra 184 OCPP disconnect after peak — Soft-offline under load/heat, prove backhaul vs controller. Field techs should co…
TRI-PK-NETTritium · PK350 · DC Fast ChargersEarly access pro+Cellular failover flapping
PK cellular failover flapping — early-access modem/SIM/DNS path before board RMA. Field techs should correlate HMI/Cloud…
DEL-UFC-COMDelta · UFC100 · DC Fast ChargersFree sampleBackend unreachable
Delta UFC100 loses its link to CSMS/cloud while the local HMI may still show Ready or Available, creating a mismatch where drivers see a working screen but the backend lists the station offline or flapping. Heartbeat gaps and delayed StatusNotification are the giveaway; sessions started locally may not sync until the link recovers.
