+- **Issue**: Server used hardcoded default extensions instead of config file settings
+- **Root Cause**: TOML key mismatch (`allowedextensions` vs `allowed_extensions`)  
+- **Impact**: XMPP file uploads failing with "File extension not allowed" errors
+- **Status**: ✅ **RESOLVED** - Configuration loading now works correctly
+
+### **XMPP File Upload Failure**
+- **Issue**: MP4 uploads from Conversations/Gajim clients returning HTTP 400 errors
+- **Root Cause**: Network resilience changes broke configuration field mapping
+- **Impact**: Mobile XMPP file sharing completely broken
+- **Status**: ✅ **RESOLVED** - MP4 uploads now work perfectly (HTTP 201)
+
+### **Mobile Network Switching**
+- **Issue**: WLAN ↔ IPv6 5G switching configuration not loading properly
+- **Root Cause**: Extension validation using wrong configuration source
+- **Impact**: Network resilience features not fully functional

+HTTP Response: 400 "File extension .mp4 not allowed"
+
+# After (FIXED) 
+Server Log: "✅ File extension .mp4 is allowed"
+HTTP Response: 201 "Upload successful"
+```
+
+### **Configuration Fix Applied**
+```toml
+# BEFORE: Not working (wrong key name)
+[uploads]
+allowedextensions = [".mp4", ".mkv", ".avi"]  # ❌ Wrong key
+
+# AFTER: Working (correct key name)  
+[uploads]
+allowed_extensions = [".mp4", ".mkv", ".avi"]  # ✅ Correct key
