Summary
The 'primary name server not listed at parent' error in MXToolbox, when using Squarespace, generally arises from a mismatch between the nameservers configured at your domain registrar (Squarespace) and those defined in the DNS zone file. The solutions revolve around verifying and correcting these records, ensuring consistency and accuracy. DNS propagation delays of up to 48 hours are common and can temporarily cause this error. Glue records are critical if your nameservers are subdomains of your main domain, requiring careful attention. Further, double-checking the SOA record, using DNS lookup tools, and ensuring A records point to the correct location can aid in identifying and resolving discrepancies. If troubleshooting doesn't work, contacting Squarespace support is recommended.
Key findings
- DNS Record Mismatch: The fundamental cause is inconsistencies between nameserver settings at Squarespace and in the DNS zone file.
- Propagation Time: DNS updates need time (up to 48 hours) to propagate across the internet.
- Glue Record Importance: Glue records are essential when nameservers are subdomains, ensuring proper delegation.
- SOA Record Significance: The SOA (Start of Authority) record must align with the configured nameservers.
Key considerations
- Record Verification: Carefully double-check nameserver records, SOA records, and A records for typos or inaccuracies.
- Use DNS Tools: Employ online DNS lookup tools (like MXToolbox) to confirm record accuracy and propagation.
- Squarespace Support: Contact Squarespace support if the issue persists despite thorough troubleshooting.
- Correct Registrar Settings: Make sure to correct the nameserver and glue record settings at the registrar (Squarespace).
