I cannot reproduce this failure. The logs contain an error message in Russian, but I'm pretty sure the English correspondent of it is:

A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

Other users have already been reporting similar. There's a strong chance that hitting this is highly dependent on the user's geographical location.

Misadov · 2022-06-15T21:41:33Z

I tried to use VPN (still allowed in Russia) and lobbies are working fine for me. Either ppy blocked russians or hosting provider set restrictions because of the current situation.

peppy · 2022-06-16T01:06:41Z

No restrictions have been set at our (or our host’s) end.

We switched cloudflare off to get better websocket reliability. We will add some fallbacks in the coming future to handle cases like yours.

You are welcome to use a VPN for now.

what ISP do you use?

edit: I could reproduce this issue on my side. With VPN it works fine, without loong loading.

My ISP is MGTS OAO (https://2ip.io/isp/OJS+Moscow+city+telephone+network/)

You are welcome to use a VPN for now.

Okay, thanks.

xDololow · 2022-06-16T17:56:44Z

My ISP is MGTS OAO

I see. I use local ISP, but it uses Megafon backbone lines.

If using a VPN gets banned another site when using VPN. How to use VPN osu!lazer application only?
I used VPN and discord not working, I uninstalled VPN and discord is working.

stanriders · 2022-06-23T22:09:14Z

Same issue, SkyNet ISP, Saint-Petersburg, Russia. Using a VPN works but is obviously far from ideal.

Pings to spectator.ppy.sh work, tracert more or less works. Fiddler shows time out, wireshark doesn't really seem to show anything useful.

peppy · 2022-06-24T04:04:46Z

@stanriders does the page load in your browser (https://spectator.ppy.sh)?

also can you confirm that the wireshark screenshot is showing bidirectional traffic (but it's only flowing in one direction)?

stanriders · 2022-06-24T06:01:30Z

@peppy the page does not load and times out, Wireshark had no incoming traffic logged from it at all.

peppy · 2022-06-24T06:07:15Z

The weirdest part is that you can ping but not get an http response. This sounds like some custom firewall rules, potentially at your ISP's end. Are you able to try and find some other DO hosted sites and see if you have similar issues?

stanriders · 2022-06-24T07:18:27Z

I'm not really sure how I can find any DO sites to test, especially considering most of the internet is going through cloudflare these days. If you have any examples I can run whatever you need

SyrokVincent · 2022-06-24T13:51:50Z

If that can help, multiplayer rooms don't load for me either, I'm in France and my ISP is "Free SAS"

https://spectator.ppy.sh/ gives me white screen
https://spectator2.ppy.sh/ - connection has timed out, can't find the page

stanriders · 2022-06-24T14:02:24Z

Speaking of, spectator2 doesn't resolve for me at all

smoogipoo · 2022-06-24T14:02:54Z

spectator2 doesn't exist anymore.

pandulce08 · 2022-06-27T15:22:53Z

Same error here, i'm from argentina.

Do you get an error or a white screen when visiting https://spectator.ppy.sh?

xDololow · 2022-07-01T09:16:53Z

Right now it gives me 404 Not Found.

peppy · 2022-07-01T09:18:01Z

Can you please take a screenshot of what you're seeing?

xDololow · 2022-07-01T09:21:06Z

Can you please take a screenshot of what you're seeing?

Chrome (says page not found)

Firefox

peppy · 2022-07-01T09:24:34Z

Are you able to test whether this site works correctly? https://www.piesocket.com/websocket-tester

It seems like you can see the server (404 response is correct) so my next theory is that somehow your ISP is blocking websocket connections.

xDololow · 2022-07-01T09:27:46Z

No problems on this one, works fine for me

peppy · 2022-07-01T09:42:43Z

And just to 100% confirm, osu! still doesn't work for you even with all the above results? Your web browser is able to connect to the server fine, so I can't think of a reason why osu! would be unable to. There has to be something more to this, especially since other users in different regions are experiencing the same thing.

Could you please provide the game's network.log once more?

xDololow · 2022-07-01T10:08:01Z

Actions I did:

Open osu!lazer
clicked to play -> multiplayer and waited a couple of minutes for it to connect (unsuccessful)
clicked back to main menu and then to playlists (loaded without a problem), opened random playlist and closed back to main menu
tried multiplayer once again, and it loaded after a few seconds.

network.log

Seems like it can load, but not always (like 1 out of 10 tries and with random success timing🗿). System.Net.Sockets.SocketException (10060) returns An attempt to establish a connection was unsuccessful because no response was received from the other computer in the required time, or an already established connection was broken due to an incorrect response from an already connected computer.

Misadov · 2022-07-01T10:54:10Z

If it makes sense, traceroute path fails on the first jump (on router) with timeout, IDK why.

(for example, there is screenshot of traceroute to site that is blocked in Russia)

)

peppy · 2022-07-01T10:55:25Z

Traceroute failing on certain hops is not an issue, and to be expected. But what you are seeing looks like your ISP is routing your packets to a black hole.

Loreos7 · 2022-07-01T11:23:19Z

For me now it looks like this

stanriders · 2022-07-01T11:33:08Z

The weirdest part is that you can ping but not get an http response. This sounds like some custom firewall rules, potentially at your ISP's end. Are you able to try and find some other DO hosted sites and see if you have similar issues?

Would you mind opening a non-standart http port to see if that works? Something like 8123 (since 8080 might be blocked too) with a hello world

pandulce08 · 2022-07-01T12:18:44Z

Same error here, i'm from argentina.

Do you get an error or a white screen when visiting https://spectator.ppy.sh?

I get a white screen on firefox and an error on chromium.

Misadov · 2022-07-05T11:33:45Z

I fixed the problem by calling the ISP and asking them to troubleshoot connection to spectator.ppy.sh. Now rooms loading and whole multiplayer is working fine for me.

peppy · 2022-07-05T11:36:15Z

Did they provide any further information about what they did to resolve this issue? If so that would be very helpful to us.

Loreos7 · 2022-07-05T11:38:15Z

I have the same ISP user Misadov has but unfortunately it doesnt work for me

Misadov · 2022-07-05T11:57:02Z

Did they provide any further information about what they did to resolve this issue? If so that would be very helpful to us.

Unfortunately no, just called and they said the tech guy didn't write comments about the problem. But no one came to my house and did not fix anything, so I can assume that the problem was on their side.
I can only add that they were only able to fix the problem when I as they said left session initialized (osu was opened for 3-4 hours at the multiplayer loading screen).

I have the same ISP user Misadov has but unfortunately it doesnt work for me

I can only advise you to try calling again. You may not have been assigned to tech support line, but left on customer support line. You can contact me in discord Misadov#3693, we can talk in russian and I will try to help you.

peppy · 2022-07-05T12:22:36Z

@Loreos7 if you do contact support, please ask for more details. also mention that you are in contact with the developers of the service and request any details which could help us potentially fix this at our end.

Loreos7 · 2022-07-05T12:52:19Z

@Loreos7 if you do contact support, please ask for more details. also mention that you are in contact with the developers of the service and request any details which could help us potentially fix this at our end.

Sure, I'll do

Misadov · 2022-07-20T15:42:03Z

I called ISP again (same issue came again) and talked with some main tech staff (I said that I in contact with developers). They said that some routes are blocked and your domain (spectator.ppy.sh) can be pinged from specific locations. I said that there is no blocking from your side, they said that this problem is global and from other ISP domain also can't be pinged. That's all information I got.

Also, main tech staff said that there is no information how issue was fixed before.

TheAirBlow · 2022-07-25T09:17:39Z

I have the same problem. My provider is OJSC Ufanet, sometimes I can visit some blocked websites.
I am an arch user too, and osu! version is 2022.723.0-lazer.

For some unknown reason I was often getting timeouts instead of 404s without VPN or Tor.

P.S. Stopped working again as of 08.14.2022

Loreos7 · 2022-08-22T10:32:03Z

@peppy
I've noticed a change with the spectator and after the last update multiplayer has gone accessible!

peppy · 2022-08-22T10:34:35Z

That's great, but we didn't change anything from our end. It may have started on a different digitalocean IP in our cluster, which would assert that certain IPs are being blocked by your ISP even more so.

Loreos7 · 2022-08-22T10:37:48Z

@xDololow @Vad1mCSO2 @stanriders @pandulce08 @SyrokVincent @TheAirBlow

You're going to need to take this up with your ISP. It's 100% not our side (or our server's side).
