I recently had the exact same issue when attempting my first PEXA conveyance. While I realise a three year turnaround might be a little too late to help Joyce, this was still the only search result for E155 errors, so here’s the solution for anyone else encountering the same problem: Verify that you have correctly entered your OSR Client ID into your PEXA profile. From the top menu, select Administration tools > Manage Subscriber Details, and then enter OSR Client ID. Verify that you have correctly entered your PEXA Subscriber ID into the Administrators tab in OSR Connect. If you need a walkthrough for this step, see https://community.pexa.com.au/t5/Share-your-Experiences/Validating-your-PEXA-Subscriber-ID-in-OSRconnect/td-p/1135.
