是系统或者防火墙原因吧,网吧的windows都不知道多久没更新了,让你的朋友找网管更新一下系统。
这里有错误代码的解释:https://support.ageofempires.com/hc/en-us/articles/4402033075476-0xfffffff-error-code

全国各地的不同网吧,并不是一个网吧。服务器证书是老问题了,证书续期失效。我查阅了steam上的电脑专家关于证书的回复,只能copy证书过来,但是无法定位帝国的ssl根证书是哪一个。

I’m getting the same issue, it also started 4 days ago (at least that’s when I first noticed, could have started a few days earlier but I didn’t try it). I’m based in Europe - not China.

I’m playing via GeforceNOW. How do you play in internet cafes? Do you install the game on the local computer? Or do you actually also use GeforceNOW?

Geforce Now says they are aware of the issue and working on a fix. Let’s hope it happens soon.

i fixed it. you need play age3(free) first time. and then fixed

What? 解决方案是先开一次帝国3?然后帝国2就正常了? :joy:

I’ve tried the AoE3 tip, didn’t help unfortunately. I’ve crossposted to reddit in case it helps anyone vent their frustration publicly:

Oh I see, apparently it’s a known issue now!
