The "DS Records" form for "Add" is incorrect: it lists available algorithms as 1, 2, 3 and 4, none of which are valid. I can't add a DS record with a valid algorithm. Attempting to add one always gives "An unexpected error has occurred."
This has been broken for about a year now.
I contacted the support team but they didnt give me any solution also, i have changed my NS records to cloudflare and is asking me to add DS records, it keeps saying
An unexpected error occurred. If this issue continues, contact support.
