Same issue, this seems very frequent these days.

[GoofyWall386651]

What worked for me is setting up my computer date 2 days behind so I put 15 of april instead of 18 of april and now it works after I restart the game.

[tahska]

their certificates expired so setting the date back makes the certificate still valid it seems

[Alyctro]

Nope, it crashes the game.

[GoofyWall386651]

exactly what I though so that’s why I tried to set the date 2 days behind. Now it works

[GoofyWall386651]

Try restarting the game

[Alyctro]

That’s what i did, but when i join a game it crashes.

I can’t even load AOE3:DE
“Unable to connect to online services, extended error. Please try again later.”

Also getting:
“You have lost network connectivity. Please check you internet connection and restart the game.”

Weird that I can post in an online forum with no network connectivity (rolls eyes)

[dknight2112]

Having the same exact issue. Played 4 multiplayer games last night. Now I’m unable to connect. Please advise.

[PantherGeist8]

i try that… it works… but i have to restart the game.

@Developers/Multiplayer Host: Please renew the certificate for AOE II https://aoe-api.reliclink.com/

Workaround: set your computer date / time to yesterday.

[Kipjr071]

I’ve submitted a bug to the developers

[Kipjr071]

It should work now. Certificate has been renewed

[niccotine]

Why do the renew for 1 year instead of 5 or 10?
Reall absurd

[dknight2112]

Working. Nice work, sir. Thanks for the submission.

[Kipjr071]

It is a HTTPS certificate. Nowadays it is common to have an one year lifespan:
The idea here is that the shorter an SSL/TLS leaf certificate’s validity period, the more secure the certificate is.

During renewal the keys are updated to the latest security standards.

Hi, i have the same certificate problem. I submitted request also, but i am wondering about how did you solved this problem ? Did the game devolopers sent you new certificates or what ?

[VladimirYevski]

Hello! I am having this problem in 2023. Can these certificates still be obtained?

[khalil_II]

Hello everyone! I also have this problem, is there a way to fix it?
