* Similar logs are found in the %ProgramData%\\CheckPoint\\Logs\\cpda.log file:

  root \[debug\] Sent request duration 109ms, Url: https://XX.XX.XX.XX:443/cp/connectionPoint/regep \[CHTTPCall_curl::sendReq_internal\]

  root \[debug\] Send succeeded, Got HTTP response body size: 273 bytes \[CHTTPCall_curl::sendReq_internal\]

  root \[info \] HTTP response code: 500 \[CHTTPCall_curl::sendReq_internal\]

  root \[debug\] Request sent using local ip 192.168.188.90 \[UpdateLocalIp\]

  <br />**

\[CHTTPCall_curl::sendReq_internal\]

<br />

* Similiar logs are found in the Endpoint Security server $UEPMDIR/logs/apache_error.log:

  \[ssl:error\] \[PID\] \[remote x.x.x.x:443\] AH02039: Certificate Verification: Error (10): certificate has expired

  \[proxy:error\] \[PID\] \[client y.y.y.y:54274\] AH00898: **Error during SSL Handshake with remote server returned by /cp/connectionPoint/regep**

* Checking the proxy_ca.pem certificate validation via SSH on the Endpoint Security server, it is expired:

  cpopenssl x509 -in $UEPMDIR/engine/conf/ssl/proxy_ca.pem -text \| grep Not

## Cause

The proxy_ca.pem certificate is expired.
