Randomly being disconnected from server. LmpCommon.Message.Data.Vessel.VesselProtoMsgData

Remember to attach the “KSP.log” and the “output_log.txt” whenever is possible!
You can find the KSP.log in “.\Kerbal Space Program\KSP.log”
And output_log.txt in “C:\Users\YOURUSERNAME\AppData\LocalLow\Squad\Kerbal Space Program\output_log.txt” (you probably need to display hidden folders to get into AppData)

In case you are using a nighly build of LMP from appveyor include the build number. For example: 0.0.9.384 Otherwise, specify the version of LMP you are using from the github releases.

If you have access to the server. Please zip the whole “Universe” and “Config” folder. Also if you are running mods in the server, attach the “LMPModControl.txt”

— KSP Log — KSP.log

— requested output log — output_log.txt

— server log — lmpserver_2018-10-13_18-32-17.log

— server universe and config files — uni and config.zip

OS: Windows 10

KSPVersion: 1.4.5.2243

---

LMP version (include the build number if you are using a nighly build): 0.14.51

---

MODS (add link to download them): None (besides LMP of course)

---

Expected behaviour: Not to be randomly disconnected

---

Current behaviour: Randomly disconnecting. Seems to occur upon launching a craft from any one player. Other people are reporting possibly during scene changes <- Unconfirmed. This error was showing from the server console when disconnects occurred: Client ShortguyGMR disconnected in Send network message error: , Endpoint 99.127.189.251:55650, error: Error serializing message!

Steps to reproduce: We seemed to be able to reproduce by simply playing for a few minutes (usually about 5-10 minutes). I would typically be knocked out of the server when someone was launching a craft while I was on the KSC scene.

If we happen to be online at the same time, if it’s ok with you I’d like to join the server with the client debugger running to see if I can catch the problem.

No all three vanilla installs and reverted back to KSP version 1.4.5. We kept trying to have 3 people playing but as soon as one of them left the problem didn’t seem to occur again.
