Domain & SSL Troubleshooting
Solutions for common custom domain and SSL certificate issues.
Domain Not Working
"Site Can't Be Reached" or DNS_PROBE_FINISHED_NXDOMAIN
| Cause |
DNS records not configured or not propagated |
| Solution |
- Verify CNAME record points to
proxy.vedtechsolutions.com
- Use DNSChecker.org to verify propagation
- Wait up to 48 hours for full propagation
- Try accessing via default subdomain to confirm instance works
|
Domain Works Sometimes, Not Others
| Cause |
DNS still propagating globally |
| Solution |
- This is normal during propagation (24-48 hours)
- Clear your local DNS cache:
- Windows:
ipconfig /flushdns
- Mac:
sudo dscacheutil -flushcache
- Linux:
sudo systemd-resolve --flush-caches
- Try a different network or use mobile data to test
|
SSL Certificate Errors
"Your Connection Is Not Private" (NET::ERR_CERT_AUTHORITY_INVALID)
| Cause |
SSL certificate not yet issued or expired |
| Solution |
- Wait 10-15 minutes for Let's Encrypt to issue certificate
- Verify DNS is correctly configured
- If using Cloudflare, ensure proxy is OFF (grey cloud)
- Check certificate status in your domain settings
|
"Certificate Name Mismatch" (ERR_CERT_COMMON_NAME_INVALID)
| Cause |
Accessing domain that doesn't match certificate |
| Solution |
- Ensure you're using the exact domain you configured
- www vs non-www matters - use the one you registered
- If you need both, add both as custom domains
|
"Too Many Redirects" (ERR_TOO_MANY_REDIRECTS)
| Cause |
Usually caused by Cloudflare proxy + our SSL |
| Solution |
- Cloudflare Users: Disable proxy (use DNS only - grey cloud)
- If you must use Cloudflare proxy:
- Set SSL mode to "Full" or "Full (Strict)"
- NOT "Flexible"
- Clear browser cookies and cache
|
Cloudflare-Specific Issues
Important: We recommend using Cloudflare in "DNS only" mode (grey cloud) for best compatibility with VedTech custom domains.
Recommended Cloudflare Settings
| Setting | Recommended Value |
|---|
| Proxy Status |
DNS only (grey cloud) - Recommended |
| SSL/TLS Mode |
Full (Strict) - if using proxy |
| Always Use HTTPS |
Off - we handle this |
| Automatic HTTPS Rewrites |
Off |
Verification Commands
Check DNS Resolution
# Check CNAME record
dig erp.yourcompany.com CNAME +short
# Should return: proxy.vedtechsolutions.com
# Check A record resolution
dig erp.yourcompany.com A +short
# Should return an IP address
Check SSL Certificate
# View certificate details
openssl s_client -connect erp.yourcompany.com:443 -servername erp.yourcompany.com /dev/null | openssl x509 -noout -dates -subject
# Quick certificate check
curl -vI https://erp.yourcompany.com 2>&1 | grep -A5 "Server certificate"
