Byond doesn't work troubleshooting guide [edited 2017/01/20]

Bottom post of the previous page:

Upon further testing with other test sites I noticed I was having 100% packet loss. So I started playing around in my my router settings and managed to get 0% loss and stable 70 ms ping on most test sites. This didn't fix the problem though, now I can connect to Bay server (which I couldn't before) but not to tg or paradise. I'm pretty sure there is something I can do in the router settings to fix it but I know shit about networks and I would be just banging rocks together

New information from discord that can assist windows 10 users

Hello. I've found that if you are on windows 10 and are relatively up to date, and have virtualization enabled on your relatively modern processor, you'll be running the device guard and credential guard hypervisor by default.

This isolates key system components using hardware virtualization and for some reason will cause byond to stutter due to I/O lag unless you make byond an exception folder. Also, device/credential guard has an optional feature called core memory isolation, and if you turn this on it'll make byond basically unplayable

even then it still causes a small and quick but noticeable stutter when moving fast when compared to running other versions of windows or even byond on wine

Mhh I broke my Byond, too.

I could play today (but had a problem with real high pings recently). Then after some break I could not start any more. I just get a connection closed window that transform after a time in the standard "check flash player" window.
I updated byond to the newest version and reinstalled my flashplayer but I still can't connect.

Any idea why?

So I am getting constant hangs. I have updated flash, enabled and disabled activex filtering, ensured the KB update was not installed and created a new user. here is where it gets weird. I cloned my harddrive, so both should have the exact same settings and the issue happens exclusively on my gaming desktop, but not my laptop

i dont think byond uses flash. it actually uses the fucking internet explorer, so try updating that

im on 515.1603 and it crashes when I click on stuff once in a while or exit out of a computer menu

also when I'm ai the sprites for the buttons are in the top right corner while the actual input region is in the normal area

change to an older version

if i do not clear the byond cache daily, opening too many huds at the same time will leave a semi-permanent white box that prevents me from seeing half of my screen that is only removed by walking away/reconnecting
another thing i've noted is that when this white hud thing will happen, item sprites on huds (such as the protolathe, crafting menu, ORM) will disappear
overall im haivng a great time

[stairmaster]

change to an older version

which one
