------------------ Openkore Issues Template ------------------

• Openkore version git: 2.1
• Server: Vietnam Official (VTC Ragnarok Online)
• Bug Report / Feature Request: Unable to connect to server (server uses nProtect Gameguard)
• Summary: I have been able to extract IP & Port and version & master_version (using Wireshark). However, I stuck at "connected"

I tried using Poseidon server also but the clientinfo.xml extracted using GRF is not similar to a clientinfo.xml template

This server uses a custom client where you login ID & PW using a Patcher-like window, then the game will show up where you choose server & character. This was my steps using Wireshark:

1) IP & Port

2) Version & Master_version: Following TCP Stream I get this

I assume that the 1st line is version (from Hex 01 to Decimal: 1)

3rd line is master_version (from Hex 61 to Decimal: 97)

Then I stuck at Timeout on Account Server.

Other things I have tried but does not work:

• WPE Pro 0.9: cannot find exe file
• RO Tool to disarm: doesnt work
• PEEK master: doesnt work
• extract_packets.pl: cannot generate recvpackets from the exe

Please help or advice where you can. Thank you very much everyone!

Let me know if you need to official game download link or the exe file uploaded.

Is this a official server? I never heard about this. Can you provide the website link so we can add to official server list?

Unpacking executable file packed with Themida is no smol task, it uses an extremely complex virtual machine environment combined with every anti-debug and anti-analysis trick in the books :(

[TheSunShower]

all is ready!

It's connected and botable now. However, autobuy caused disconnection, autosell works, and autostorage requires encryption key.

Lockmap sometime get stuck and requires reboot to work normally. Not sure if it is because of autosell.

[ya4ept]

@TheSunShower autosell is fixed: #3458 give me money for kafra, my name is kirama

[chumlacklx]

Glad to see everyone support on vRO. Thank so much

Packet Parser: Unknown switch: 0918

Auto attack works.

Self buff works.

Attack Skill require using names from referenced tables.

[alisonrag]

Auto attack works.

Self buff works.

Attack Skill doesn't work, it just stares at monsters. Config as followed:

Main Config:

attackAuto 2 attackDistance 8 attackUseWeapon 0 lockMap yuno_fild08

Skill Blocks:

attackSkillSlot Cold Bolt { lvl 10 dist 8 sp > 18 inLockOnly 1 notInTown 1 monsters Grand Peco }

attackSkillSlot Fire Bolt { lvl 10 dist 8 sp > 18 inLockOnly 1 notInTown 1 monsters Geographer }

seems like skills name are different, check: https://github.com/OpenKore/openkore/blob/master/tables/vRO/skillnametable.txt

type skills in console and try to use the same name, also try with: MG_FIREBOLT and MG_COLDBOLT

[Pureaznangel]

Use skill Id, instead. => Info => Skill to get one.

[TheSunShower]

The disconnection that happens frequently might be related to access token from VTC being timed out (No Msg 243)

On ROClient, a logout/login is required to restart a launcher with a timed out token

On OpenKore, need to physically close Terminal and relaunch OpenKore. If not it will gradually stack relog timer.

[ya4ept]

RO client can run longer than openkore without restarting? I need a test account with skills

[TheSunShower]

Example of disconnection on OpenKore

Connecting to Account Server... Connecting (roacc1.vtcgame.vn:6900)... connected Disconnecting (IP:6900)...disconnected The server has denied your connection for unknown reason (243).

this is the point where OpenKore cannot reconnect itself anymore.

[ya4ept]

try this #3459

[PhiLongXP]

try this #3459

Token is alive in 1 hour only, so renew when connect that should work.

Maybe this is ping-back send every 10 minutes. If there is no response in 3 times (resend every minute), will be disconnected from Map Server.

[playboyvntgn]

@ya4ept I can't use auto storage because they need EncryptKey. Do you know EncryptKey of vRo server? I appreciate your help!

[TheSunShower]

I can't use auto storage because they need EncryptKey.

Fixed in latest master.

[playboyvntgn]

I can't use auto storage because they need EncryptKey.

Fixed in latest master.

Thank you I got it.

I have one more error, that's I can't use warp skill. After I cast it on ground, the bot disconnected immediately.
