A little insight goes a long way. Find your next good read.
Changing a cPanel primary domain requires hosting support, not self-service, because it's a WHM-level root account change. At NameSilo, request via 24/7 live chat; the hosting team rebuilds the plan, typically within a few hours. Back up all files and databases first; data is not recoverable.
SPF ~all (SoftFail) marks unauthorized mail as suspicious but delivers it to spam. SPF -all (HardFail) rejects it outright. Start new deployments with ~all, monitor DMARC reports for 2-4 weeks, then switch to -all once your sender list is confirmed complete.
405 errors mean the server rejected the HTTP method, not that the page is missing. Check the form's action URL and method first; this resolves most cases. Also inspect .htaccess for Limit/LimitExcept directives and check for caching or security plugin conflicts.
Cargo's current platform uses nameserver delegation, not A records. Point your domain to ns1.cargo.site and ns2.cargo.site from NameSilo's Domain Manager, then add the domain in Cargo's Publish Settings. Requires an active Site Upgrade. Email records are preserved automatically.
A primary nameserver is the writeable master zone file; a secondary is an automatic read-only replica synced via zone transfer. Both typically answer live traffic simultaneously, not just as passive backup. Domains require at least two nameservers; NameSilo supports up to 13 per domain.
MX priority determines mail server order; lower numbers are tried first. Google Workspace now uses a single record (smtp.google.com, priority 1); other providers like Titan Mail use tiered priorities (10, 20). Never give two different providers the same priority; mail will split unpredictably.
Create a coming soon page in cPanel via Sitepro site builder or manually in File Manager: public_html, create index.html in lowercase, paste basic HTML. Delete existing default index files first. All NameSilo hosting plans include both tools.
Connect custom domain to Adobe Portfolio: add 4 A records in DNS (2 IPs × root and www). Find IPs in Portfolio Settings → Domain Name. Delete conflicting records first. Do not re-enter domain more than 5 times. SSL provisions automatically. 24-48 hours to propagate.
DNS audit checklist: verify A records, audit CNAMEs for dangling records (primary subdomain takeover vector), validate SPF/DKIM/DMARC, check nameserver consistency. Use MXToolbox and SecurityTrails. Remove all records from decommissioned services. Audit quarterly.
Public Wi-Fi captive portals intercept DNS and redirect to a login page. HTTPS blocks this redirect causing SSL errors. Fix: disable VPN and mobile data, visit http://neverssl.com to trigger the portal. Custom DNS like 8.8.8.8 can also block portal detection.
Connect custom domain to Render: A record @ → 216.24.57.1, CNAME www → yourapp.onrender.com. Delete AAAA records first. Render uses IPv4 only. Cloudflare users: use CNAME, set DNS only mode before verification. SSL provisions automatically via Let's Encrypt.
Add rua=mailto:[email protected] to your _dmarc TXT record to receive daily XML aggregate reports. Use a dedicated inbox, not your primary address. Parse reports with Dmarcian or MXToolbox. Start with p=none before enforcing. RUF forensic reports are optional.
