Zoho CRM -> SDP MSP Integration - Not Working in Recent Months

Zoho CRM -> SDP MSP Integration - Not Working in Recent Months

Issue:
We are having an issue with our Zoho CRM -> SDP MSP integration. We are unsure when in stopped working, as it did work in the past, but it appears it may have broken around January of this year (2025).

Info:
- SDP MSP On-Prem, v. 14.9 Build 14930
- Free Standard License

Although it did sync in the past, LastSync shows as NA. Pressing Sync Now presents a confirmation that the sync was successfully started, but no events appear in the log when this is performed. We also recreated the existing Self-Client in Zoho API Console, and re-did the integration steps in the docs here

To my knowledge, the free license supports this integration, according to here

We recently updated while troubleshooting, it also failed to work in the following versions:
- 14830
- 14840

Is anyone else experiencing this issue?
