From Clash to V2RayN: Unlocking SOCKS5

So recently, Clash has been performing well based on this setup.

But I ran into an issue when switching to V2Ray.
(v2rayN on Pop_OS, if that matters.)
I could connect to my node just fine on my phone - but not on my PC.
And when I tested all node delays in v2rayN, they all looked normal and green.

So, based on the previous setup, I’m gonna troubleshoot a few key points
to make sure we can switch to V2Ray smoothly.

---

🚪 Proxy port setup

Check out your V2Ray mixed port(normally it should be 10808).

Edit your ~/.bashrc or ~/.zshrc and Comment the proxy setup for Clash, add one for v2rayN export all_proxy="socks5://127.0.0.1:10808".

# 🌩  Clash Proxy for tools like curl/pip
#export http_proxy="http://127.0.0.1:7892"
#export https_proxy="http://127.0.0.1:7892"
#export all_proxy="socks5://127.0.0.1:7891"

# 🌩  v2rayN Proxy for tools like curl/pip
export all_proxy="socks5://127.0.0.1:10808"

---

Use this alias if you’ve used my previous setup.

git-proxy-v2ray

Or if not:

git config --global http.proxy http://127.0.0.1:10808 && git config --global https.proxy http://127.0.0.1:10808

---

Then reload:

source ~/.zshrc

or

source ~/.bashrc

🧪 Test with:

curl -x socks5h://127.0.0.1:10808 https://api.myip.com

Failed with error code: 1005? Check if this part helps!

🦊 Make Firefox obey proxy

Go to:

Firefox → Settings → Network Settings → Manual Proxy Configuration Set:

• SOCKS Host: 127.0.0.1
• Port: 10808
• No proxy for: localhost, 127.0.0.1
• Check “Proxy DNS when using SOCKS v5”

Now test your IP & DNS servers with BrowserLeaks - it should work instantly.

---

💢 TUN Conflict Check (if you used Clash before)

Check if there’s leftover tun0 or custom route:

ip a
ip r

If you see 198.18.x.x, fake-ip, or utun, kill them:

sudo ip link delete tun0
sudo ip rule flush
sudo ip route flush table main
sudo systemctl restart NetworkManager

---

🧹 Lock in Clean DNS

If you’re running systemd-resolved, and your DNS is:

nameserver 127.0.0.53  ← stub resolver (systemd-resolved)

Yet behind the scenes, it’s actually forwarding to router,

for example, static:

1.1.1.1
8.8.8.8

Now Just change /etc/resolv.conf (keep systemd-resolved)

sudo rm /etc/resolv.conf # Remove symlinked `resolv.conf`
echo -e "nameserver 1.1.1.1\nnameserver 8.8.8.8" | sudo tee /etc/resolv.conf # Create static one
sudo chattr +i /etc/resolv.conf # Make it immutable (no more random override!)

Change 1.1.1.1 and 8.8.8.8 to your router DNS.

🔄 if you ever wanna revert:

sudo chattr -i /etc/resolv.conf
sudo ln -sf /run/systemd/resolve/stub-resolv.conf /etc/resolv.conf

This is totally safe and revertible. This way you skip the stub resolver, send DNS direct to your router’s DNS servers (e.g. Cloudflare/Google).

---

❗ About the 3 lines in /etc/resolv.conf

Line	Meaning
nameserver 127.0.0.53	Stub resolver - systemd-resolved interception
options edns0 trust-ad	Extended DNS flags - fine to keep or ignore
search .	Domain search - totally safe to remove or leave, it does nothing here

You only really need to change the nameserver to your desired DNS.

🧪 Final test: sudo reboot + launch v2rayN + use SOCKS

curl -x socks5h://127.0.0.1:10808 https://api.myip.com

Get error code: 1005?

Try these:

curl -x socks5h://127.0.0.1:10808 https://httpbin.org/ip

# Set Custom User-Agent
curl -A "Mozilla/5.0" -x socks5h://127.0.0.1:10808 https://icanhazip.com

# Try one of these known good APIs:
curl -x socks5h://127.0.0.1:10808 https://ifconfig.me
curl -x socks5h://127.0.0.1:10808 https://ipinfo.io/ip
curl -x socks5h://127.0.0.1:10808 https://icanhazip.com
curl -x socks5h://127.0.0.1:10808 https://wtfismyip.com/text

🔍 What Is Cloudflare error 1005?

That means:

🔒 Access Denied - Your IP has been flagged (by WAF, rate-limits, or country ban)

Cloudflare does this:

• If the IP is in a VPN range
• If the proxy IP is suspicious (many access requests)
• If your TLS signature, headers, or behavior looks bot-like
• Or if the site owner blocks entire countries

api.myip.com uses Cloudflare, and your node’s IP is probably on a list if you got error code: 1005.

🧠 All set! What’s Working Flawlessly Now (Based on my test)

App	Result
Discord	✅ YES
Spotify(flatpak)	✅ YES (No Proxy)
Chrome	✅ YES
Telegram	✅ YES (needs SOCKS5 manually configured, similar with firefox’s)
VSCode Git	✅ YES
HexChat	✅ YES
Firefox	😐 Set manually or use system proxy settings

🎵 Here’s the Spicy one - About Spotify ads

So far, I’ve found two actually useful ways to block Spotify ads.

• Spotify Web + uBlock Origin
• Spotify Desktop: Route it through your V2Ray proxy - exactly what we set up earlier!

✅ Spotify Desktop = NO ads, but only when it’s running through V2RayN + private & clean nodes.
❌ Clash Verge + Rule mode? That doesn’t phreakin’ work.

What might be going on inside SOCKS5?
Honestly, I’d love to know…
