Enable DNSSEC in OVH

When I try to create the DS Record in OVH to activate DNSSEC I get this message:

An error has occurred requesting to change the DNSSEC keys. (Public key should be encoded in Base64)

As I can check the key is already in Base64 so this message does not make sense to me.

Anyone that have enabled DNSSEC in OVH to give me some tips?

I found the issue and is not related to OVH but to HestiaCP, when I execute v-list-dnssec-public-key I clearly see that the key has a space in between.

All the domain DNSSEC keys are being shown with a space in between what makes the base64 encoding to not be valid.

Just remove the space and it works fine
