Mailjet SPF & DKIM to DigitalOcean

Hi guys,

I try to setup an mail server by Mailjet.com to my DigitalOcean Discourse 2.0.220180802 Droplet. So I added a domain to the droplet that dircets to the discourse server.

Domain: example-community.de
A     example-community.de     directs to 46.101.***.***          3600 
NS    example-community.de     directs to ns1.digitalocean.com.   1800
NS    example-community.de     directs to ns2.digitalocean.com.   1800 
NS    example-community.de     directs to ns3.digitalocean.com.   1800

Also in Mailjet: Add domain example-community.de

Host: mailjet._d780712a@example-community.de
Value TXT: d780713ae1560f4e28d8f15e8048271 

Then i add a DNS recod to DigitalOcean

Type TXT
Hostname: mailjet._d780712a
Value: d780713ae1560f4e28d8f15e8048271

so it looks like:

TXT    mailjet._d780712a.example-community.de    3600

Now try to validate, but it fails.

If I switch to edit domain in Mailjet, there are also: SPF-Record:

example-community.de.
TXT: v=spf1 include:spf.mailjet.com ?all

and DomainKeys/DKIM

mailjet._domainkey.example-community.de.
k=rsa; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDh/72U9BmklM5b19iKfsPsrTD54YIvjar4Li+p+zFmGqP3

Where is my mistake?

Thanks for helping
