I have been unable to connect to my server. I keep getting this error. http://pastebin.com/UsiGy7VG

I have forwarded the port.
Added Firewall exceptions for KSP, KSP64, and DMP
Verified my Cache.

I cannot think what else I can do and I am at a loss.

i am sorry to inform you but i get this same issue on a fresh ksp install (version 1.1.3) with both the devbranch and 2.3.1. so it seems that its still an issue.

all Firewall settings have been checked, heck i even shut down the firewall completely. all to no avail

Could you provide your KSP.log file (upload to Pastebin)?

sure of course, here you go:

When checking the log the error seems different from the one that Chazz was experiencing,
my instance seems to be throwing a divide by zero exception:

@callmebackdraft try deleting your Universe folder on the server and restart it.

My universe folder is empty, however i still tried deleting it to no avail

What server version are you using?

Server and client version 2.3.1 atm but also tried both dev versions

Can you please create a new issue reporting the error you're getting? As you said before, it is unrelated to the error the OP had, and it's better to keep track of.

I will do that first thing in the morning (its midnight over her right now)
Thanks for investigating the issue so far.

I'm aware of this issue that says TimeWarp.SetRate is an invalid method, however, I can't find why it occurs. Until then, no fix :(

Okay.

any news about this? :
Unknown sent connection end message, reason: Unhandled error while syncing!
