In this case there is a problem with the IPSec certificate on the server and you need to regenerate it, delete the ipsec-trust certificate, and load a new one. Complete these steps in order to address the issue:
- Log onto the OS Administration page.
- Choose Security > Certificate Management > find.
- Click ipsec.pem file and then click regenerate.
- After the successful generation of the ipsec.pem file, download the file.
- Go back to the certificate management page.
- Delete the current corrupted ipsec-trust entry.
- Upload the downloaded ipsec.pem file as a ipsec-trust.
- Restart DRF Master and DRF Local.
