DNS Failure
Issue
Via proxy sometimes occur an error "DNS Lookup for safesqddns.com failed".
Root Causes
- The FQDN of the website is incorrect.
- The local DNS server service is not running.
- The forwarder DNS server is not able to resolve the query.
- The network service is down.
Solution
If the FQDN of the website is incorrect you will face a DNS failure issue to that website while accessing via proxy. So, you have to enter the correct FQDN of that particular website.
If the FQDN of a particular website is correct but the local DNS server service is not running still you can face a DNS failure issue. So, you make sure that the local DNS server service is running.
Run the below commands to verify DNS server service
nslookup (FQDN of the site)
example:
nslookup www.safesquiddns.com
Server: 127.0.0.1
Address: 127.0.0.1#53
Non-authoritative answer:
www.safesquiddns.com canonical name = safesquiddns.com.
Name: safesquiddns.com
Address: 164.177.149.146
If the website is not able to resolve
root@dev:~# nslookup www.safesquiddns.com
Server: 127.0.0.1
Address: 127.0.0.1#53
server can't find test.safesquiddns.com: NXDOMAIN
