I'm not sure what's happenning on mudfish nodes because when I checked your status, your connection between your desktop and mudfish japan nodes are all fine. If I'm not sure that you can access with mudfish, did you try to play the game without mudfish or with other VPN providers? Sometimes it could be caused by game server networks.

I cannot play/connect to mobile suit guundam online without using a Janapanese VPN. I did not use other VPN providers while I am using mudfish to connect. But some of the lines e.g. Sakura Tokyo has been very unstable in terms of connetion speed which rendered the game very slow and unplayable. This game only performs normally without lag only if the VPN server/node has an RTT under 60

When I looked your core logs, I'm seeing the following messages:

[2022.227665] [ERROR] re18: MUDEC_00262: ODR_sendto() error to 153.121.43.118: Message too long. Check your path MTU. (curmtu 1450 buflen 1464)
[9683.455862] [ERROR] MUDEC_00235: Too many heartbeat errors. Blocked by network firewalls?

These error means that MTU (Maximum Transmission Unit) between your desktop and mudfish node is small than what you're set as default value of mudfish.

To address this issue, you can try to change the MTU value of TAP-Win32 adapter v9 network adapter with smaller value. Its default value is 1500 (bytes). However it can try with small value (e.g. 1400, 1350, 1300 or a value you'd like to try). I think first you should fix this problem for efficient network packet delivery.

Thanks very much for your help and response.
I have set the MTU at 1329. There was less stuttering and slow motions. However, there was no improvement in terms of RTT especially Sakura Tokyo. I had to swap among the nodes which had the lowest RTT(e.g. IDC 1to 3, sakura and connoha) continuely to avoid lags and delay.
Will try lower MTU settings tomorrow t see the results.

Okay and thank you for your feedback. Please let me know if it seems the problem is caused by mudfish node.

Sorry. problems resume again. :(

When I checked your core logs on server side, I can see the following messages.

[10881.786403] [ERROR] MUDEC_00235: Too many heartbeat errors. Blocked by network firewalls?

Could you please check that the basic functionality is working correctly with following Quickstart for v4 link? Or one thing you can try is 'Connection Protocols' link to change your connection protocol if it seems network firewall blocked UDP packets.

Quickstart for v4: 'It seems everything works fine. :-) ' message.
I don;t have any LAN at my home. Just a laptop directly connected to the internet through PPPOE, so there should be no network firewall. If that firewall exists at the point of my Internet service provider which blocked UDP, I should not have been able to play the game at all in the first place.
Have changed to TCP, seems not as good as UDP. Any other explanation for the Heartbeat error?
Cause tonight there was one time IDC node 3 halted and the game freezed when I was playing.I then swap to Sakura which was also very laggy.

To clarify your heartbeat issue, please check mudfish code logs which be available at 'Dashboard -> Status -> Process'. At there you can find some heartbeat related error messages. And if you don't mind, you can send me the Problem Report to send me detail logs.

And for halting issue of mudfish nodes, I feel sorry for this inconvenience. It seems ISP providing mudfish nodes forcibly restarts my boxes to remove Xen security vulnerability. :-( It should be okay now.

thank you. Report sent

Please see my comment at below. :-)

sorry. Tonight. Linodes IDC 3 halted again

Sorry for this inconvenience. When I checked the system log, I'm seeing that your private IPv4 address of mudfish was conflict with other mudfish users. It looks that problem caused your issue. To address this issue permanently, it seems I need to patch server daemons and clients too. When your issue happen again, at this moment it'd be better to restart Mudfish itself. I'll release new version as soon as possible to address your issue.

Thank you so much

@glau912 how did you setup to connect to msgo? i have been trying for a while now to connect to msgo but i get the same error message.

What problem did you have when connecting? Please be specific. Not all Japanese nodes can connect to MSGO.

Tokyo - Linode1 IDC stuttered and halted imtermittently seriously again. Unplayable. please look into it!!

Not all nodes work, I suggest you to try SakuraNet.

> Tokyo - Linode1 IDC stuttered and halted imtermittently seriously again. Unplayable. please look into it!!

Sorry for this inconvenience. Depending on the mudfish node status, sometimes the node encounter unexpected high traffics (e.g. caused by users using Full VPN mode) because each mudfish nodes are shared by all users. If then, you might be better to use other mudfish nodes to avoid network congestion.

Good thing that RTT of Conoha 1,2 have improved a lot.
thumbs up!!

Do you still need help with playing msgo with mudfish i can make a video
