I’ve got a few tips/ hints for you guys to reduce the random disconnects etc. but they do not work against the random crashes. (Evolve just close itself for no reason and put you back to the dashboard)
Choose your internet provider carefully
For example In Germany (my homeland) the internet provider Unity media got mayor problems with the Xbox one console. My provider is Telekom and i have no problems at all with my connection.
Choose your router carefully
I’ve got a Fritzbox and prefer it over a Speedport etc. It’s important that you can tweak most options like fixed IP.
Open your NAT
There are some hints for specific routers, i recommend to search replies for that problem on google.
As a general rule you have to open specific ports for your xbox on your router. (use google please)
Also it helps to set the IP of your xbox to fixed.
There’s is also a mayor problem with the IPV6-connection, the xbox can’t handle this at all, you have to use IPV4 exclusively to bypass this issue. I recommend to put your IPV6-connection completely off.
Mostly newer OS for the routers can enable/ disable this option, therefore you have to update your router to the newest OS.
When all works your xbox connection test say NAT: open.
Than go to the IP-options in your xbox and look for your primary DNS! When you see something like 192.168.178.1 (your router-IP) than all is ok but if you see something like 1ksw.p48n.db6u.be00z you will have a problem. Often in this case the problem comes from your IPV6-connection and you should turn it off.
When someone in the lobby/ party chat doesn’t get an open NAT he can disrupt your connection as well.
In this case help him to open his NAT or you will struggle with this problem forever.
If you leave multiple times a menu /game in Evolve the matchmaking will struggle to find you players and you can not join a friend’s game.
I think this is some kind of ram issue with Evolve.
To solve this problem just restart the game! (also your buddies)
I hope that will help a little bit guys.
