## Symptoms

- * Device Agent was installed successfully, but the Endpoint Client fails to register with '`error code 7 (== couldn't connect).`'  

* *%DADIR%\\Logs\\cpda.log* file on Endpoint Client shows:  

  *DATE TIME*` [CPDA] Sending msg type REGISTER_ENDPOINT, no_zpdoc, https, <IP_Address>, 443, /cp/connectionPoint/regep, exec EP auth handling: no, authType: DEVICE (CCPPeer::send)`  
  *DATE TIME*` [CPDA] Sending HTTP request, body size: 273, URL: https://<IP_Address>:443/cp/connectionPoint/regep (CHTTPCall_curl::sendReq)`  
  *DATE TIME*` [CPDA] ---ERROR--- Failed to send request/receive response due to HTTP curl library function curl_easy_perform returned error code 7 (== couldn't connect). Last win error: 0 (0x0) (CHTTPCall_curl::sendReq)`  
  *DATE TIME*` [CPDA] ---ERROR--- CURL error description: Connect failed; Timed out. Last win error: 183 (0xB7) (CHTTPCall_curl::sendReq)`

  *DATE TIME*` [CPDA] ---ERROR--- Failed to register endpoint. Last win error: 183 (0xB7) (CDA.threadMethod)`  

* Alternatively, there is a failure to create a state of trust between the Endpoint Policy Server and the Endpoint Security Management Server, with the following error message:  

  `SIC Status for CP: Unknown`  
  `Could not establish TCP connection with <CP_IP_Address>`  
  `Check that CPD is running on CP and that TCP connectivity is allowed from the SmartCenter server to IP <CP_IP_address>, Port 18191.`

## Cause

The Windows Server Firewall is blocking Check Point communication.
