Hello,
I would like to report what appears to be a Bedrock connectivity issue affecting AMP-managed Bedrock instances.
Environment:
-
AMP version: 2.7.2.8
-
Docker networking mode: Host
-
Debian VPS
-
AMP running inside Docker
-
Bedrock Dedicated Server managed through AMP
Issue:
Players receive “Connection Timed Out” when attempting to join the server.
Troubleshooting already performed:
-
Verified Docker networking mode is set to Host.
-
Verified Bedrock server is listening on UDP 19132.
-
Verified firewall is not blocking traffic.
-
Verified Hostinger network infrastructure is functioning correctly.
-
Verified bidirectional UDP traffic using tcpdump.
-
Tested multiple ports.
-
Tested with addons enabled.
-
Tested with addons disabled.
-
Tested with a completely clean Bedrock instance.
-
Tested different client devices.
Network verification:
tcpdump shows inbound packets reaching the VPS and outbound packets being sent back successfully.
Example:
Client → VPS UDP 19132
VPS → Client UDP 19132
Traffic is exchanged correctly.
Server verification:
ss -lunp confirms:
bedrock_server listening on 0.0.0.0:19132
Version testing:
RESULTS:
-
Bedrock Server 1.26.23 = WORKS
-
Bedrock Server 1.26.30.5 = FAILS
-
Bedrock Server 1.26.31.1 = FAILS
The same VPS, same AMP installation, same network configuration and same environment works correctly on 1.26.23 but fails on both 1.26.30 and 1.26.31.1.
Additionally, Hostinger support reviewed the investigation and confirmed that:
-
VPS networking is working.
-
Docker host networking is working.
-
Firewall configuration is working.
-
UDP packets are successfully exchanged.
-
The issue does not appear to originate from the VPS infrastructure.
Question:
Has anyone observed Bedrock 1.26.30+ timing out during the connection handshake when running under AMP on Debian?
Is there any known issue, patch, workaround, or configuration change recommended by CubeCoders for Bedrock 1.26.30 / 1.26.31?
Thank you.
