# Fix Local DNS — Complete Guide
|
|
|
|
**Last Updated:** 2026-01-31
|
|
**Document Version:** 1.0
|
|
**Status:** Active Documentation
|
|
|
|
---
|
|
|
|
**Issue:** `DNS_PROBE_FINISHED_NXDOMAIN` for explorer.d-bis.org, explorer.defi-oracle.io, and all endpoints.
|
|
|
|
**Cause:** Your device/network DNS (ISP, router, or cached) is not resolving these domains. Cloudflare and Google DNS resolve them correctly.
|
|
|
|
---
|
|
|
|
## Quick Fix (Run This)
|
|
|
|
```bash
|
|
sudo ./scripts/fix-local-dns-hosts.sh
|
|
```
|
|
|
|
This will:
|
|
1. Add 21 domain entries to `/etc/hosts` → 76.53.10.36
|
|
2. (WSL) Set `/etc/resolv.conf` to use Cloudflare DNS (1.1.1.1, 1.0.0.1)
|
|
3. (WSL) Add `generateResolvConf = false` to `/etc/wsl.conf` so DNS persists
|
|
|
|
**Note:** If you can't use sudo, run without it to see the hosts entries — then add them manually with `sudo nano /etc/hosts`.

|
|

|
|
|
|
## Verify
|
|
|
|
```bash
|
|
# Should return 76.53.10.36
|
|
getent hosts explorer.d-bis.org
|
|
|
|
# Should return HTTP 200
|
|
curl -sI https://explorer.d-bis.org/ | head -3
|
|
```
|
|
|

|
|
|
|
## Alternative: Force Cloudflare DNS (No hosts file)
|
|
|
|
**WSL** — Create `/etc/wsl.conf`:
|
|
```ini
|
|
[network]
|
|
generateResolvConf = false
|
|
```
|
|
|
|
Then set `/etc/resolv.conf`:
|
|
```
|
|
nameserver 1.1.1.1
|
|
nameserver 1.0.0.1
|
|
```
|
|
|
|
Restart WSL: `wsl --shutdown` (from PowerShell), then reopen your terminal.
