Hello ServiceNow Community,
We are configuring an outbound REST Message inside ServiceNow Integration Hub to send JSON payloads to an external intake endpoint (hdclaims.co.uk).
Issue Description:
When executing the outbound HTTP POST request via a MID Server script inclusion, the transaction times out after 10000ms with a java.net.SocketTimeoutException: Read timed out error. Executing the same payload directly from Postman completes in under 350ms.
Environment Setup:
Instance Version: Washington DC / Xanadu Release
Authentication: OAuth 2-0 / Bearer Token
Target Domain: (hdclaims.co.uk)
Steps Taken:
Verified that the ECC Queue displays status error during payload transmission.
Imported the target server root CA certificate into the ServiceNow System Definition Certificate store.
Disabled TLS 1-3 session ticket resumption on the server proxy, but the MID Server socket read timeout persists.
Is there a specific system property (glide.http.timeout_retry) or socket connection pool limit in ServiceNow that needs adjustment for custom .co.uk web application endpoints?
Any technical guidance would be greatly appreciated!
