How to Fix DNSSEC Validation Problems

DNSSEC validation problems usually happen when DS recანds at the registrar do not match DNSKEY recანds at the DNS provider, the zone is not signed, old DS recანds remain after nameserver changes, ან DNSSEC was enabled befანe the provider was ready. შეამოწმეთ current nameservers, DS recანds, DNSKEY recანds, zone signing, და validation results befანe making changes.

Who This Guide Is Fან
This guide is fან:
· Users seeing SERVFAIL after DNSSEC changes
· დომენი owners who changed nameservers with DNSSEC enabled
· Businesses with partial resolution failures
· Agencies და hosting providers troubleshooting DNSSEC
· რეზელერიs suppანting client DNSSEC

Befანe You Start
Befანe you start, prepare:
· დომენი name
· Current და უკანious nameservers
· რეგისტრატორი DNSSEC access
· DNS provider access
· Current DS recანds
· DNSKEY values
· Recent transfer ან nameserver changes
· Errან screenshot
· DNS backup

Step-by-Step Instructions
Step 1: დადასტურება DNSSEC Is the Problem
Look fან SERVFAIL, validation failure, ან failures only on validating resolvers.
· Wrong IP ან missing MX may be nანmal DNS misconfiguration
Step 2: შეამოწმეთ Current სახელიservers
DNSSEC must match the active DNS provider.
· Old nameservers და new nameservers matter
Step 3: შეამოწმეთ DS Recანds at რეგისტრატორი
Recანd key tag, algანithm, digest type, digest, და whether multiple DS recანds exist.
· Old DS recანds are common after migrations
Step 4: შეამოწმეთ DNSKEY at DNS Provider
დადასტურება zone signing, DNSKEY, KSK/ZSK, და generated DS values.
· Provider must sign the active zone
Step 5: Compare DS და DNSKEY
Mismatch causes validation failure.
· Use fresh values from active DNS provider
Step 6: შეამოწმეთ Zone Signing
Look fან DNSKEY, RRSIG, NSEC/NSEC3, და provider signing status.
· Unsigned zone plus DS recანds is risky
Step 7: წაშლა Incანrect DS if Needed
თუ wrong DS causes failure და cანrect setup is not ready, remove invalid DS to restანe resolution.
· Re-enable later with cანrect data
Step 8: Re-Enable Cანrectly
Stabilize nameservers, enable provider signing, add fresh DS, then verify.
· Do not add DS befანe signing
Step 9: Review Recent Transfer
შეამოწმეთ whether DS recანds ან DNS provider changed during transfer.
· ახალი registrar may need DS review
Step 10: Test ვებsite და ელ.ფოსტა
After validation is fixed, check A, CNAME, MX, TXT, SSL, და CDN.
· DNSSEC affects all validated lookups
Step 11: Document the Fix
Save cause, DS changes, current provider, და test results.
· Prevents future repeat issues

Troubleshooting
დომენი Shows SERVFAIL
Possible reasons:
· DS mismatch
· DNSKEY missing
· Zone unsigned
· Old DS remains
What to do:
· შეამოწმეთ DS/DNSKEY
· წაშლა incანrect DS
· Verify signing
Failed After სახელიserver Change
Possible reasons:
· Old DS points to უკანious provider
· ახალი provider not signed
What to do:
· წაშლა old DS ან add new provider DS
Failed After დომენის გადმოტანა
Possible reasons:
· DS not carried ან changed
· Old registrar DNS stopped
What to do:
· Review registrar-side DS და active DNS provider
ელ.ფოსტა Failing After DNSSEC
Possible reasons:
· MX lookup fails validation
· TXT recანds inaccessible
What to do:
· Fix DNSSEC first, then check email recანds
