Steam client goes 'NO CONNECTION' every single day

[renmccourtey]

Hi, I have Steam client installed on both my laptop and of course my main gaming PC. Each time I wake one computer, the other client soon goes to NO CONNECTION. It was annoying for years, but I lived with that, using laptop on week and gaming PC on weekends mostly. But since recently, when the 3rd client arrived (yes, Steamdeck), this became offline hell. All of them are NO CONNECTION state all the time, as I use these various systems throughout a day lately. As you can imagine, official support was completely useless, pasting some generic answers about deleting browser cookies and closing the ticket afterward, pointing me to community support. Unbelievable. Anyway, is this know behavior? Is there any known workaround to keep them all online? Could this be some sort of NAT issue or is it just a client limitation...?

Part of steam network Trouble shooting guide.

Known Issues with Internet Service Providers (ISPs)
Important:
If you notice that your Steam connection only has issues during certain hours of the day (for example in the evenings between 5pm and 11pm), it is possible that your ISP is blocking or "shaping" your connection. Please test your connection at other hours of the day and contact your ISP directly if you believe this is causing the connection issue.

Some ISPs have been found to block ports required for the proper operation of Steam and Steam games:
012.net (Steam traffic blocked)
Bluewin (Firewall blocks Steam from provider side - must be disabled through provider's service portal)
Dutch Telecom (Steam traffic blocked)
ISPFree (Steam traffic blocked)
Micronet Broadband (Steam traffic blocked)



Ask own ISP, ipv6 or other issue related to network, even own security try safe boot mode.

Hi iceira. What exactly should I ask my ISP? I mean, I already described how the issue works, it's related to multiple running client instances and I can replicate it freely anytime. IF it would be network related, the cause would be in my router but I can hardly believe Steam client would be so oversensitive. The troubleshooting guide, which I did carefully read already by the way, doesn't point in uPNP, NAT config or similar direction. I did a few experiments with forwarding the required ports but it surprisingly made no difference.

I could try to mess around with Wireshark but I doubt I would identify the root cause this way. This thing has to make some logs, doesn't it? It should be as easy as looking into one text file but support didn't offer any guidance in this.

I sit on 500Mbit business-class cable connection, there is no chance the provider would interfere in any way.

This has nothing to do with ISPs.

This is the intended Steam client behavior. Steam servers are intentionally 'disconnecting' - or rather, telling you about it.

The Steam client works like a web app. Unless you click on something that requires a HTTP_request style client page update, the Steam client 'hibernates' to allow tens and hundreds of thousands actual requests per minute to connect to the Steam servers.

It also seems to be a way to defeat DDOS attacks, but I have no inside knowledge on that.

Usually, when you click on something or start a game, the connection will be re-established and your session 'ticket' will be updated instantly, after you are next in the queue.

you are mixing up something here, ( all other is online 24/7/365, only way im not online is if connection is gone by isp or i shutdown my end or pc )

Technicaly it dont explan what cause this, its just that trafic is not there as is was then online, it dont say why or who.

im on fibercable , so watchour for own network or bad traffic like wifi or weak or to fare away to wifi router even that can trigger it or bounce at wall if door is closed or a person is the blocking area, so technicaly anything goes here. even ISP or congessted network and thats ISP in my case. i could even give 100% CPU Load time then sync can fail to connect to steam on older pc, diffrence is i know i did it, and as OP try to figure out what cause this.

[Iceira]

Do have right country and clock in sync, ( some ppl forget they did time cheat in a game and can give system issue , require pc cold boot to correct windows system. ) i did not say you did , i said some other did that. and then it work again. according to them.

ps.
i only know such from log entry have right time index can matter in a global communication, you cant find someting thats dont match search timeindex. ( thats how it was discover and might not be related to you at all )

ps.
any pc that OC could get out of sync or not do its connection in time ( 3 way handshack establish the connection then it will go offline ( apps that use 100% cpu in my case can cause such ) most will say dont fit my case and thats true, check pc for idle status and learn such then start steam did that help. ?

not the first time i have hear person with old pc say pc take over 5 minute to startup ( no one in right mind will ask a gamer about such ) most will get a rage, but i bet, most adult person really dont care and think its normal then pc boot up at morning, dont think gamer will accept such.

this is why i wrote it , so other can learn other things can cause issue, most will not even mention such, and that issue is over 3 years and older and most still have not Identify all the cause by this.


ps.
other have said to many apps start at same time then booting, you need delayed startup and now we are over in ( out of sync or timeout in connection ) so steam go offline.

if you dont understand this im sure other helper can explan, maybe better then there is so many what if this and that here.

[Iceira]

And OP be happy this is now offline all the time, thats even better then on or off and even worse to Identify, now you actual have a baseline its offline, you might not see it , but any car mecanic cn tell you yeah its working now then you show it, thats not funny for any customer.

you now have much higher chance to solve this, and what cause this.



dont forget this is a user forum and i and other here, dont have any information other then you bring here.
assume 1 router as standard setup that connect to ISP, and no i will not waste my time on 2, because require expert knowledge.

OK guys, I know you're just other users of Steam just like me (that's why I'm so pissed off on Steam support, they do not provide any tech support and are just impudent to send me to ask in community, that's bold move for billion dollar company). Anyway, you clearly didn't really read the issue as I described it.
tl;dr: When I start Steam client on another computer, the previous one goes to NO CONNECTION mode and basically stops working (most pages doesn't really load anymore on that one). Simple as that. With Steam deck in my possession now it become a real PitA.
