Plutonium

Hi team,

I'm the owner of the Warden | AU East servers (T6, r5338). Reporting an issue and sharing what I've observed in case the data is useful. I'll leave the interpretation to you.

Symptom

• Players intermittently can't see my servers in the in-game browser. some can, some can't, at the same time.
• Servers appear otherwise healthy: console logs Heartbeat successful. continuously, and players can connect via direct IP.

Observations from my host

• The heartbeat goes out as an HTTPS request to nix plutonium pw and completes successfully (matches the Heartbeat successful. log line).
• Anonymous HTTPS GET to nix plutonium pw and plutonium pw returns HTTP 403 with the Cloudflare "Attention Required" (error 1020) page. This happens on every path I tried, including the root.
• A browser User-Agent on the same request also returns 403.
• The host is a datacenter/hosting IP.

Environment

• Game: T6, Plutonium r5338
• Server: Warden | AU East
• Time observed: Started around 6PM AEST

Questions

• Is anything on the master side currently expected to affect server visibility, and is there anything I should check or change on my end?
• If a Cloudflare Ray ID from one of the 403 responses would help you look into it, I can provide one privately.

Thanks.

How did you solve this because I have triple checked all my settings and all 6 of my T6 servers went offline. They're all orchestrated via Docker and can confirm connecting directly is working perfectly fine it just fails to display on the server list... Tried new keys, new IP and nothing!

Setup
T5MP dedicated server r5334 on Linux (Debian, Wine 9.0, Docker), game files from my own Steam copy (app 42700, Windows depot). Launched via:

bin/plutonium-bootstrapper-win32.exe t5mp /path/to/Server/ -dedicated +set key XXX +set fs_game "" +set net_port 21892 +exec dedicated.cfg +map_rotate

The server boots fine: fastfiles load, dedicated.cfg execs, map rotation set, DW auth completes (DW_AUTHORIZED -> DW_LOGON_COMPLETE), and heartbeats succeed. But it endlessly loops:

Parsed 0 reserved slot passwords
SESSION CREATE ERROR 2103
Session creation failed. Killing server
MATCHMAKINGDEBUG: Calling updatesession...
Server: Updating session - serverinfo change
Session update error!

---

RECREATING SESSION

---

reauthenticating dedicated server!
DW_AUTHORIZED -> DW_LOGON_COMPLETE
SESSION CREATE ERROR 2103 (repeats forever)

2103 = 0x837 = BD_INVALID_SESSION_ID.

Already tried:

• Fresh server key created specifically for T5MP (not reused from another game)
• Removing all custom dvars from the launch line
• Fresh Plutonium files via plutonium-updater (r5334)

A T6MP server on the same host/network works perfectly (heartbeat, listing, players joining), so outbound connectivity and NAT are fine. Game UDP port is forwarded.

Is error 2103 on session create a known backend issue for T5MP dedis (similar to the old T5SP session errors), or is there something server-side I should check? Does this affect joinability/listing, or is it safe to ignore?

This has to be the most annoying thing. I am the owner of Warden | AU East T6 MP and it's only been up for 3 days and I am constantly under DDoS attack.

Provider refuses to do anything about it even though they can support up to multiple terabit hits.

Same with the influx of cheaters that just rock up. I have a day job and cannot spend every waking second banning people...

No worries Rekinator. Makes sense.

Cheers for the update Luigi. I'll stay tuned to the Discord for an announcement.

luigistyle Will there be a native dedicated server for Linux instead of going through the Wine way of doing things?

Hi Forum.

I don't want to sound like a broken record but is anyone aware of a status update for Linux Dedicated Servers?

Cheers.
