Most "won't connect" and "too slow" cases come from how the proxy was entered or from two apps fighting, not from a broken IP. Each of the six checks below takes a minute or two, and most problems are fixed on the spot.
"Won't connect" means the app reports a timeout, an authentication failure or a 407 error, or pages keep loading forever. Go through checks 1 to 4.
"Slow" means pages open, but each one takes several seconds, or the connection comes and goes. Do checks 1 to 4 first, then check 5 and the section "If it is slow" below.
Either way, finish with check 6: open https://ipinfo.io/json through the proxy. If the page opens and the IP and country match, the proxy works.
Use the address that My assets shows for this IP, without changing a single letter. If it shows proxy.proxy302.com, enter proxy.proxy302.com, not us.proxy302.com. If it shows us.proxy302.com, enter us.proxy302.com. The entry is enabled per IP, so switching to the other address yourself only gets you an authentication error.
Expected result The address in your app matches My assets character for character.
Before continuing Do not change the address yourself. If you are in Asia outside mainland China, My assets shows us.proxy302.com and the proxy feels slow, open a ticket with this IP and we will move it to an entry closer to you; the login, password and port stay the same. If you are in mainland China and it feels slow, open a ticket too, and we will advise based on your network.
Take the port from My assets and make sure the type (protocol) matches it: HTTP is usually 2222, SOCKS5 is usually 3333. SOCKS5 with port 2222, or HTTP with 3333, will not connect. If an asset says "HTTP only" or "SOCKS5 only", use that one.
Expected result Type and port both match My assets.
Put only the login in the login field and only the password in the password field; do not paste a whole link into either. If you were given one string such as socks5://login:[email protected]:3333, split it like this: the login sits between "//" and the first ":", the password between ":" and "@", the address between "@" and the next ":", and the number at the end is the port. Watch for spaces at the start or end when you copy.
Expected result Each field holds one piece of text, with no "socks5://" or "@" in it.
Clash, Shadowrocket, a VPN app, another accelerator or the One-click boost of the Proxy302 helper tool: only one of them should handle your connection at a time. With two on, they overwrite each other's system proxy settings, the entry often ends up pointing at your own computer (127.0.0.1), and neither works. In Clash, use Rule mode. In Clash or Shadowrocket, do not keep a VPN's global mode or TUN on at the same time (TUN is a virtual network adapter that takes over all traffic on the device).
Expected result Only one proxy app is running in the taskbar, the menu bar or the phone's VPN indicator.
In AdsPower and similar antidetect browsers, put the Proxy302 type, address, port, login and password straight into the profile's proxy settings. Do not enter Clash's main port (often 7890 or 7897): the exit would then be the IP of whatever node Clash has selected, not the IP you bought.
Expected result The browser's proxy check shows the country and IP you bought.
Open https://ipinfo.io/json through the proxy; on a phone, http://ip-api.com/json works too. If the IP is not your own and the country matches what you bought, the proxy works. If it shows another IP (for example a VPN's), the traffic is not going through Proxy302: go back to checks 4 and 5. In phone apps such as Happ, a ping of N/A or a failed speed test does not mean the proxy is broken; the web page is what counts.
Expected result The page opens, and the IP and country match.
Check Is the address the one My assets shows? Are the login and password in separate fields, with no extra spaces and no whole link pasted in?
Fix Put back the address from My assets; split the login and password again as in check 3.
Check Do the type and port match? Are two proxy apps on at once? Has the IP expired, or has the traffic run out?
Fix Fix as in checks 2 and 4; renew or top up in My assets if the IP has expired or the traffic is used up.
Check Where are you, and which entry does My assets show? Is a VPN's global mode or TUN on at the same time?
Fix Turn off the VPN's global mode and TUN; in Asia outside mainland China with us.proxy302.com in My assets, open a ticket to move to a closer entry; in mainland China, open a ticket and we will advise based on your network.
Check Did you enter Clash's main port (often 7890 or 7897) in the app or browser? Is another VPN on at the same time?
Fix Enter the Proxy302 address and port instead, and turn the other VPN off.
Check With the proxy on, open http://ip-api.com/json in the browser: does it show the IP you bought?
Fix If the page looks right, the proxy works; ignore the ping figure in the app.
Check Check the formatting of the Clash extended configuration: indentation and the space after each colon.
Fix Fix the formatting, save again, and check that the Proxy302 node is in the node list.
Rule out app conflicts first: turn off the VPN's global mode and TUN, and keep only one proxy app. Much of what feels slow is traffic going to a VPN first and only then to Proxy302, so it travels two legs instead of one.
Then look at the entry. If you are in Asia outside mainland China and My assets shows us.proxy302.com, every new connection takes a longer path. Open a ticket with the IP and we will move it to a closer entry; the login, password and port stay the same. Once it is done, change the address to the one in our reply. If you are in mainland China and it feels slow, open a ticket with the IP as well, and we will advise based on your network.
Judge speed by how fast pages open, not by the ping figure in an app.
| Item | Type | Address and port | Login and password | Watch out for |
|---|---|---|---|---|
| Clash Verge | socks5 or http, as in My assets | server and port from My assets | username and password on separate lines | Rule mode; not together with another proxy app or the helper tool's One-click boost |
| Shadowrocket | SOCKS5 or HTTP, as in My assets | Address and port from My assets | User and password in separate fields | No VPN node in global mode at the same time |
| Happ | socks | Address and port from My assets | Split the login and password out of the string | A ping of N/A is normal; ip-api.com/json is what counts |
| AdsPower and other antidetect browsers | HTTP or SOCKS5, as in My assets | The Proxy302 address and port, entered directly | Login and password in separate fields | Not Clash's main port 7890 or 7897 |
My assets is the console page that lists every proxy you bought. The settings come from connection tickets handled in November 2026; menu names may differ after an app update.
Open a ticket in the console and include the following, so we can find the cause faster:
• The IP: as shown in My assets, or the address plus the login.
• Your country or city, and the device and app you use, for example Windows + Clash Verge, iPhone + Shadowrocket, Android + Happ, or AdsPower.
• Screenshots of checks 1 to 6 and of the ipinfo.io/json result. You can blur the password.
The entry is enabled per IP, and only the address shown in My assets works for it. To move to a closer entry, open a ticket with the IP; once we have switched it, change the address on your side.
No. Both take over the system proxy, so together they overwrite each other, the entry ends up pointing at your own computer, and neither works. Keep only the one you use.
With the proxy on, open http://ip-api.com/json or https://ipinfo.io/json in the browser. If the IP and country match, it works. The ping figure in the app is only a hint.
First confirm with ipinfo.io/json that the exit is the IP you bought. If it is and the site still won't open, the site may have its own limits or checks; the ERR_PROXY_CONNECTION_FAILED guide explains how to tell whether the problem is the proxy or the site.
The ERR_PROXY_CONNECTION_FAILED error appears in Chrome and Edge when the browser cannot establish a connection with a proxy server.
HTTP 407 Proxy Authentication Required comes from the proxy server, not from the website you are trying to reach.
Every working proxy is described by five basic fields: protocol, host address, port, login, and password.
How to add an HTTP or SOCKS5 proxy in Clash Verge and other mihomo-based clients, and check the exit.
Add a Proxy302 HTTP or SOCKS5 proxy to Shadowrocket on iPhone: which boxes to fill, how to switch it on, how to check your exit IP and what to do in mainland China.
What to check when AdsPower says "Connection test failed" or a profile reports a proxy failure: type, fields, validity, network, VPN, then confirm the exit IP.
Check the exit IP, country and ISP your proxy really gives you in 30 seconds — and why IP databases disagree on the city. With our own test of three lookup services.
Product observation · Confirmed on:
Connection tickets handled in early November 2026 on Windows with Clash Verge and AdsPower, and on phones with Shadowrocket and Happ: the setup mistakes that stopped a connection or slowed it down, and the settings that fixed them. No customer data is published.
Third-party source · Confirmed on:
Read in full on 28 October 2026: the system proxy writes the listening port into the place the operating system keeps by convention and apps read it voluntarily — not all programs comply, and it cannot proxy UDP; Tun mode creates a virtual network adapter that takes over all TCP/UDP traffic, independent of developer cooperation, with no extra per-app configuration; routing modes are rule / global / direct; Clash Verge Rev uses the Mihomo (Clash Meta) core.
