Can't estabish connection in 0.17, worked fine in 0.16. Not sure what's up.

Post by npuldon »

Hello,

For some reason folks are having a impossible time connecting to me on 0.17 when I used to host all the time on 0.16 without issue. They get the "Could not establish connection..." error. I can connect to their games without issue. I have a strong 90 Mb/s wired connection on Comcast. I'm playing vanilla on steam, latest experimental.

Here is the end of the my log file when someone was trying to connect. Are these messages normal?

What else can I do to deduce the issue here?

EDIT: One of the discord admins helped me out to test this stuff. I setup port forwarding and he was able to join me now where he wasn't before. It's just odd because I never needed to do that pre-0.17 with same hardware/setup on my end. Oh well.


On another note, if a game on the public list says "Can't reach" under the ping field but I can still join the game with a few seconds delay before it actually connects, what's going on here?

Thanks for the report. What you're experiencing is unofficially known as "home routers" and there's nothing (that we can afford) to work around the problem.
If you want to get ahold of me I'm almost always on Discord.
