From Clash to V2RayN: Unlocking SOCKS5
A smooth walkthrough switching from Clash to V2RayN on Linux: fixing port conflicts, bypassing ads on Spotify, and fine-tuning SOCKS5 proxy magic that just works.
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:
1
git config --global http.proxy http://127.0.0.1:10808 && git config --global https.proxy http://127.0.0.1:10808
Then reload:
1
source ~/.zshrc
or
1
source ~/.bashrc
🧪 Test with:
1
curl -x socks5h://127.0.0.1:10808 https://api.myip.com

🦊 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:
1
2
ip a
ip r
If you see 198.18.x.x, fake-ip, or utun, kill them:
1
2

4
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:
1
nameserver 127.0.0.53 ← stub resolver (systemd-resolved)
Yet behind the scenes, it’s actually forwarding to router,
for example, static:
1
2
1.1.1.1
8.8.8.8
Now Just change /etc/resolv.conf (keep systemd-resolved)
1
2
3
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
1.1.1.1and8.8.8.8to your router DNS.
🔄 if you ever wanna revert:
1
2
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

🔍 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…
