Alternatively a thread dump produced by this would also move us in the right direction:

Oh, for ***** sake. You've made me popped up on this forum once again.
This long living problem is caused by MTU. And, I do believe, loftar found a solution for this problem and successfully implemented it in HaH, it was mentioned in one of the patches. I think you should ask him about that.

Problems with MTU were never equally reproducible for different ISPs, that's why it's hard to catch and fix them. But almost certainly they can be avoided with VPN-proxies, i.e. https://www.privatetunnel.com
Anyone, who has "black screen" problems shoud give it a try... at least - to confirm problems with MTU.

Have fun.

If I might say so, I doubt that. I would understand that being the problem if the problem were an indefinite loading screen, but not really with a totally black screen. A totally black screen rather seems to indicate that some thread has hung.

Highly doubt that. You don't put any "loading..." message after logging in. I mean, in the character selection screen, right at the moment when your client is starting to communicate with server over UDP.
That's why these guys have "totally black screen" - because there are nothing in between.

Someone should do a tcpdump or wireshark while this is happening. This will tell them if the MTU is not high enough or if something other is going on

Oh, is this happening directly on login, even before character selection? Sorry, didn't read the whole thread, will look at that.

Indeed, the tile-info packet had grown large enough to be fragmented at the IP level. There's a case to be made that people whose routers refuse IP fragmentation should get fukked, but at least that makes it easy to fix.
