Baseline
2026
Newly available
Since April 2026, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
The sctpCauseCode read-only property of the RTCError interface provides the SCTP cause code explaining why the SCTP negotiation failed, if the RTCError represents an SCTP error.
Value
A positive integer specifying the SCTP cause code explaining why the error occurred.
This property must only be set if errorDetail is sctp-failure, and is otherwise null.
The standard SCTP error cause codes, numbered 1-13, are defined in the SCTP specification: RFC 4960, section 3.3.10.
