Sulky has been getting teh following error and disconnect from the servers.
"Signature Check timed out"
"Sulky disconnected from the server."
Found this on a forum that might relate to Sulky and anyone else who is getting this error.
QuoteIt is related to signature check.
If it is your server, adding
regularcheck="{}";
to your server config will probably help.
If you are having this problem with other servers, there is nothing you can do other than taking off some addons/mods.
i was just about to post that ;-)
although i am reinstalling arma and removing all mods to see what happens
to continue with the info on this it appears to be only happening on the domination and insurgency missions as every normal mission that ive been on has worked fine
