Given how long you said it's been down it looks like you've run into a GDPR problem. ICANN shows the following regarding your domain.
Name Server: NS73.DOMAINCONTROL.COM Name Server: NS74.DOMAINCONTROL.COM
URL of the ICANN WHOIS Data Problem Reporting System: http://wdprs.internic.net/ >>> Last update of WHOIS database: 2018-05-28T09:00:00Z <<< For more information on Whois status codes, please visit https://www.icann.org/resources/pages/epp-status-codes-2014-06-16-en Notes: IMPORTANT: Port43 will provide the ICANN-required minimum data set per ICANN Temporary Specification, adopted 17 May 2018. Visit https://whois.godaddy.com to look up contact data for domains not covered by GDPR policy.
Also the following info is at the bottom of the page:
On 17 May 2018 the ICANN Board adopted a Temporary Specification for gTLD Registration Data. https://www.icann.org/resources/pages/gtld-registration-data-specs-en
This page is under review and will be updated to address the Temporary Specification.
I don't know much about GDPR. We as a company don't keep any customer data on outside servers and don't provide service to anyone that falls under the jurisdiction of the GDPR laws. According to our attorney, since we have no customer information protected by GDPR we don't have any issues. Our compliance officer is in charge with that though so it's possible I'm wrong about our company but I really don't need to know. I just need to know who's head to ring if we get it wrong. lol
My guess is that something about the build of your website is not compliant so it's being blocked. I would review that doc in detail including the link inside the doc and then call godaddy and ask them what it will take to get it back up so you can get it done.
