    It seems you have only uploaded device certificate and it is using old device certificate key and due to this you are facing this issue.

     

    It should be having access to cli, i think so. You can take F5 login through WINSCP and go to below device certificate and key path.

     

    /config/httpd/conf/ssl.crt/server.crt

    /config/httpd/conf/ssl.key/server.key

     

    At above path, you should see certificate imported by you. Do one thing, put key file associated with new device certificate at above key location and then restart 'httpd' service of F5 by using cli command - bigstart restart httpd

     

    Your issue should get resolve with this. But you should have access to SCP for this.

     

    I hope it resolves your access.
