+# 🔧 Git Connection Fix
+
+## Issue
+```
+fatal: unable to access 'https://git.dk0.dev/denshooter/portfolio/': 
+Failed to connect to git.dk0.dev port 443 after 75002 ms: Couldn't connect to server
+```
+
+## Solutions
+
+### Option 1: Check Server Status
+The server is reachable via HTTP (tested), but Git might need authentication.
+
+### Option 2: Configure Git Credentials
+```bash
+# Store credentials
+git config --global credential.helper store
+
+# Or use keychain (macOS)
+git config --global credential.helper osxkeychain
+```
+
+### Option 3: Use Personal Access Token
+1. Go to: https://git.dk0.dev/user/settings/applications
+2. Generate a new token
+3. Use it when pushing:
+   ```bash
+   git push https://YOUR_TOKEN@git.dk0.dev/denshooter/portfolio.git
+   ```
+
+### Option 4: Check Firewall/Network
+- Port 443 might be blocked
+- Try from different network
+- Check if VPN is needed
+
+### Option 5: Use SSH (if port 22 opens)
+```bash
+git remote set-url origin git@git.dk0.dev:denshooter/portfolio.git
+```
+
+## Current Status
+- Remote URL: `https://git.dk0.dev/denshooter/portfolio.git`
+- Server reachable: ✅ (HTTP works)
+- Git connection: ⚠️ (May need credentials)
+
+## Quick Test
+```bash
+# Test connection
+curl -I https://git.dk0.dev
+
+# Test Git
+git ls-remote https://git.dk0.dev/denshooter/portfolio.git
+```
