Copado's backend has 4 static IP addresses. If you have IP restrictions in your Salesforce org, you may need to whitelist them in Setup > Network Access.
Make sure of the following:
- If there are IP restrictions at the profile level, you will also need to add these addresses in the Login IP Ranges section of the Profile.
- In Setup > Session Settings, the checkbox Enforce login IP ranges on every request is not enabled.
- In Setup > Session Settings, the checkbox Lock sessions to the IP address from which they originated is not enabled.
