Getting error BXNUI2081E while uploading certificate files

[frkncngz]

I am getting the following error at the upload step:

Attempting certificate upload...
Uploading certificate to domain 'xxxxx.co'...
FAILED
Error response from server. Status code: 500; description: BXNUI2081E: <b>The certificates and keys were not modified because an unknown error occurred: Error.</b> <br>Click the <b>Account and Support</b> icon in the top menu bar, click <b>Get help</b>, and search for help or get support..

Warning: Please note that your SSL certificate, its corresponding PRIVATE KEY, and its intermediate certificates have been downloaded to the current working directory. If you need to remove them, use `rm *.pem`
Unable to upload certificates

I also tried to upload the files by using the following command but still getting the same error.

bx security cert-add xxxxx.co -k privkey.pem -c cert.pem -i chain.pem

What might be the reason?

Strangely it disappeared by itself 🤔
