0 DS RR in the parent zone found

DS-Query in the parent zone has a valid NSEC3 RR as result with the hashed domain name between the hashed NSEC3-owner and the hashed NextOwner. So the parent zone confirmes the non-existence of a DS RR.

Aname "exchange.spvusd.org" is subdomain, public suffix is "org", top-level-domain-type is "generic", tld-manager is "Public Interest Registry (PIR)"
Agood: All ip addresses are public addresses

ADNS: "Name Error" means: No www-dns-entry defined. This isn't a problem
Agood: destination is https

Misconfiguration - main pages should never send http status 400 - 499
OOld connection: Tls.1.0 is deprecated, Tls.1.2 should be supported
OOld connection: SHA1 as Hash Algorithm is deprecated. Switch to SHA256 or SHA384. If your certificate has SHA256, first check your domain via ssllabs.com and update weak Cipher Suites. Forward Secrecy support is required. The part "Cipher Suites" should have a preference. First Cipher Suite with SHA instead of SHA256 or higher - that's the problem, change that. If that doesn't help, check if there is an old Firewall / router or something else, that supports only SHA1. Update that component.

403

Fatal: Check of /.well-known/acme-challenge/random-filename has a http status 401 / 403 Not Allowed / Forbidden . Creating a Letsencrypt certificate via http-01 challenge can't work.
AGood: Domainname is not on the "Specially Designated Nationals And Blocked Persons List" (SDN). That's an US-list of individuals and companies owned or controlled by, or acting for or on behalf of, targeted countries. It also lists individuals, groups, and entities, such as terrorists and narcotics traffickers designated under programs that are not country-specific. Collectively, such individuals and companies are called "Specially Designated Nationals" or "SDNs." Their assets are blocked and U.S. persons are generally prohibited from dealing with them. So if a domain name is on that list, it's impossible to create a Letsencrypt certificate with that domain name. Check the list manual - https://www.treasury.gov/resource-center/sanctions/sdn-list/pages/default.aspx
