If your infrastructure implements IP whitelisting, make sure that you add these IPs to the allowed origins, so that requests from Quality Clouds are not blocked:
All servers located in: EU (Ireland)
22.214.171.124 → 126.96.36.199 188.8.131.52 → 184.108.40.206 220.127.116.11
Important Note - 19 October 2022.
Due to changes in our infrastructure, the IPs in our EU cluster have changed. Please replace the old IPs (grayed out) with the current ones in your whitelist.
