Persistent map loading delays– CDN/routing issue (not local)

Hello everyone,
I am experiencing a persistent performance issue that has been ongoing for a long time (approximately a year), and I wanted to share my findings here in case other players are experiencing the same, and to request proper investigation from the technical team.

The symptoms:

• Black/grey screen for several seconds when changing maps
• Noticeable delay when opening NPC shops or selling items
• During group gameplay in maps, severe lag occurs — I cannot interact properly with monsters, item drops are delayed, and I cannot follow what is happening in real time. This makes group content essentially unplayable.

What I have already tried (local troubleshooting ):

• Full reinstall of the game client (multiple times)
• Clearing temporary files and DSO client folder cache
• Flushing DNS cache
• Testing Google DNS (8.8.8.8) and Cloudflare DNS (1.1.1.1)
• Disabling background services (SysMain, Windows Search)
• Closing all background applications and overlays
• Testing both WiFi and wired (Ethernet) connections
• Running the game from SSD storage
• DMZ configuration on router
• Changing router settings

Network test results:

• Download speed: ~80 Mbps, Upload: ~10 Mbps
• Ping to grimmag.drakensang.com: 42–47ms, 0% packet loss
• Traceroute reaches game server IP in 7 hops with stable latency
• ISP confirmed no issues on their side

Client log findings: The game logs clearly show two recurring server-side issues:

1. CDN asset loading failures: IoChannelHandler: failed to open stream 'httpnz://alicdn-prod-774.drakensang.com/...' Failed to load resource 'tex:...'
2. Server-side disconnection: RakNetClient::HandleDisconnectionByServer(): Kicked by server (47. etc.)

These errors appear consistently and are not related to local hardware or ISP performance.

VPN test results: When connecting through a VPN (European server), the map loading delays are slightly reduced (approximately 2–3 seconds improvement), but the issue does not fully resolve. This suggests a combination of routing inefficiency from Bigpoint network, AND a CDN-side issue with asset delivery.

All local troubleshooting has been exhausted. The evidence points to two server-side issues:

1. The CDN node alicdn-prod-774.drakensang.com is failing to serve game assets reliably
2. The game server is terminating sessions unexpectedly (Kicked by server)

I am asking:

• Has anyone else experienced this ?
• Can a moderator please escalate this to the technical team for CDN and server-side investigation?

I have attached ping results, traceroute, client logs, and DXDiag report as supporting evidence to support but they clearly told me they are not willing to investigate my case !

Thank you for your time.

veeeeeeeeeeeeeeeeeeery slow
I think your speed is too low.
