# SCM Connection - "Could not connect to the server"

**Symptoms**

* After entering your SCM URL and token, Mobb returns a "could not connect to the server" error.

**Likely cause**

Mobb (or the broker) cannot reach the SCM URL, the URL is incorrect, or a network/proxy/ certificate issue is blocking the connection.

**Resolution**

1. Double-check the SCM server URL for typos and confirm it's reachable from the broker's network.
2. For on-premises SCMs, verify the broker is running and healthy — see [My broker can't reach the SCM](/mobb-user-docs/common-troubleshooting-scenarios/broker-cannot-reach-scm.md).
3. If the SCM uses an internal certificate, ensure certificate validation is handled (for the broker, `TARGET_DISABLE_CERT_VALIDATION=true`).
