Why network isn't working after changes of proxychains4

sudo nano /etc/proxychains4.conf Dynamic chain is open. Then, I #/comment others(strict chain,random chain,round robin chain) Another changes I made socks4 125.26.99.2 44052. Then, I run proxychains on firefox proxychains firefox google.com After few minutes : They are loading loading and loading................. I don't know why this is happening. Those websites aren't opening... My proxychains filename is proxychains4 that's why I thought it would work if I run the following command proxychains4 firefox google.com Nonetheless, I am getting same error
