What should I do if the proxy cannot connect?

Please check the following in order:

• Whether the proxy address, port, username, and password are correct;

• Whether the HTTP/HTTPS protocol is used;

• Whether residential proxies are using port 9999;

• Whether sub-regions such as state and city are filtered simultaneously;

We recommend selecting only the country, regenerating the proxy link, and testing again. You can also use the following command:

curl -x "proxy_address:9999" -U "username:password" "https://ipinfo.thordata.com"
