NG proxy ip failure solution: NGINX proxy troubleshooting

NG proxy ip suddenly strikes? Look at these three places first

Don't panic when you encounter NGINX proxy suddenly jerking, 90% problems are in these three places:Configuration file has drifted.,IP is blacked out by the target website,Internet connection jerkThe first thing to do is to check the address after proxy_pass in nginx.conf. First, check if the address following proxy_pass in nginx.conf is correct, and don't reverse http and https. For example, the target station is https protocol, you paired with http://backend_server, then absolutely can not connect.

 Correct Demonstration
location / {
    proxy_pass https://backend_server; proxy_set_header Host $host; proxy_set_header
    proxy_set_header Host $host.
}

If the code is okay, immediately use thecurl -x Proxy IP:Port Destination URLManual test. Returning 403 or timeout? Odds are the IP is being winded.

The Wildcard Solution to IP Blocking

Many brothers encountered IP blocked only change IP, in fact, you can try toReducing the frequency of requests, such as adding a speed limit module to nginx:

limit_req_zone $binary_remote_addr zone=one:10m rate=1r/s;

location / {
    limit_req zone=one burst=5;
    proxy_pass https://backend_server;
}

If that doesn't work, go straight to the high anonymity IPs. this is a must.ipipgo's Static Residential Package, their IPs are all real life home broadband, with the pseudo degree pulled full circle. If you've used it, you'll know that 35 bucks for an IP will last you a month, which is much more cost-effective than changing dynamic IPs seven or eight times.

The Hidden Killer of Stuck Connections

Sometimes the proxy configuration is fine, but it just gets stuck in theTLS handshake failureorCertificate mismatch. Adding these two lines in nginx saves lives:

proxy_ssl_server_name on; proxy_ssl_protocols TLSv1.2 TLSv1.3;
proxy_ssl_protocols TLSv1.2 TLSv1.3;

If the target site uses SNI (Server Name Indication), remember to add theproxy_ssl_name $host. If you can't get it right, just switch toipipgo's TK lineThey automatically handle SSL certificate issues without even changing the code.

Practical QA Handbook

Q：Why does dynamic IP always prompt "connection reset"?

A: Dynamic IP survival time is short, it is recommended to add in nginx configurationproxy_connect_timeout 15If you want to change your IP address, you can use ipipgo's Enterprise Dynamic Residential at $9.47/GB to set up an automatic switching period, which is much more stable than manually switching.

Q: What if I need to go through multiple agents at the same time?

A: In nginx withupstream module for load balancingThe IPs are extracted in bulk with ipipgo's API:

upstream proxy_pool {
    server 192.168.1.1:8000;
    server 192.168.1.1:8000; server 192.168.1.2:8000;
}

location / {
    proxy_pass http://proxy_pool; }
}

Ultimate Weapon Selection Guide

Lastly, I'd like to talk about a tawdry operation: installing the ipipgo client on a home NAS and setting it up as a secondary proxy. This way all devices can go proxy, but also do not have to configure each machine separately. Specific tutorials are available on their website, just follow the copy homework.
