I am adding additional information to assist you with the ssl upload.
as an example: upload certificate “ca2_1.crt.pem” to Thunder use CURL
curl -F upload=@ca2_1.crt.pem -k https://$ip/services/rest/V2.0/?session_id=$session\&format=json\&method=slb.ssl.upload\&type=certificate
I have attached additional shell script in this thread to fix your ssl upload problem. Change the certificate name match your environment. Run the script like this: ./ssl-upload.sh
