Host error during request eTicketCouponLLSRQ

Question

Sometimes I receive ERR.SWS.HOST.CONNECTOR_ERROR while invoking eTicketCouponLLSRQ and sometimes I receive valid response. What is wrong? Thank you!

I'm working in CERT, SRW version is 2.15.2 (SDK version), PCC Z4KB, EPR 1112

This is likely a timeout on a Sabre backend, meaning that it was not able to process it.

If you get many of this, I recommend you to contact the Sabre API helpdesk
