=== How to trace cUrl error (6) Could not resolve host === | |||
This DNS resolution error indicates the hostname doesn't exist. Here are the 3 key debugging steps: | |||
1. Verify the main domain exists | |||
<pre> | |||
curl -i https://example.com | |||
</pre> | |||
2. Check subdomain DNS resolution | |||
<pre> | |||
nslookup subdomain.example.com | |||
</pre> | |||
3. Test correct URL structure | |||
<pre> | |||
# Maybe it's a path instead of subdomain | |||
curl -i "https://www.example.com/subdomain/..." | |||
# Or try common subdomain alternatives | |||
nslookup www.example.com | |||
nslookup api.example.com | |||
</pre> | |||
Conclusion: If you get {{kbd | key=NXDOMAIN}}, the subdomain doesn't exist - verify the correct URL from your source. | |||
