Their servers are borked since the summer sale ended, lots of stuff hasn't been working for days all we can do is wait until they fix it...it's happened before after a sale seems they can't learn from their past mistakes, takes them forever to fix, maybe same dev messing stuff up they need a new one.

What a drug !! Thanks for the answer, I had forgotten it, and I was really seeing that this happened a few other times, 2017, 2020 and a few other times. I just reinstalled Steam, restarted the PC and for now it worked again. I hope will not give this problem again.

I started having same issue last week. Now I cant download any games from my library and cant update them. Also I am stuck with trying to download SteamWorks Common Redistributables. It downloads like 190.5 mb's and then speed of download goes to zero and download halts saying "content unavailable". Same goes for mods for ArmA3 in Steam Workshop.
I tried changing region of download in my settings, clearing download cache, I used command "steam://flushconfig" and tried to delete some of the files manually and run Steam.exe as administrator. I restarted my PC, router and Steam multiple times as well.
As of yet I have no luck and the problem persists. In my 15 years of experience with Steam this is the first time I have anything like this!

Well, at least I am not alone struggling with this issue. It's good to know it is probably not on my end.

going to steam-settings-downloads-clear downloads cache fixed it for me

Guys, I reinstalled steam and it worked here, I didn't want to have to download the game all over again, so I just cut the Steamapps folder, reinstalled steam and then pasted it back so I didn't have to download everything again.

I guess I would have to try this one out if situation doesn't improve soon...

Does anyone know why this is happening and what exactly has changed that is causing it to act up in Windows 7?! I'm still trying to figure out why the Steam server is refusing to allow Windows 7 users to download some games but not others. TLS 1.2 and 1.3 are also up to date. So what's missing here?

As of May 21st, 2025, Valve has updated their compression algorithm to be more CPU and I/O efficient.
This change is not compatible with old clients that could still run on Windows 7 and future content changes will be made using this compression algorithm, resulting in a loss of access to downloads and updates.

As Valve has ended support for Windows 7 since January 1st, 2024, and therefore won't update their client for the use of Windows 7, your officially supported options are:
* Upgrade to Windows 10 (End of Life by October 2025 unless enrolled into ESU)
* Upgrade to Windows 11
* Install Linux Mint and play Windows only games using Proton

Thanks, my friend! :) So it's a strange compression issue after all...
Is there any way to patch it somehow?
Is this feature in Steam a combination of a feature from/in Windows 10?

You can't patch it. It's a change in the Steam client which breaks compatibility with old clients. The above options are your only officially supported ones.

Content Servers Unreachable
It started this morning, July 15, 2025, around 2 a.m.! No servers can be accessed, games can't be updated, games can't be downloaded, or anything... Message: Content Unavailable or Content Servers Unreachable.
I reset my router, restarted Steam, and restarted my PC, but nothing.
I cleaned the download too and nothing

Steam is down for routine maintenance every Tuesday.

1. Which of the options mentioned do you mean?

Maybe I missed something. Or just misunderstood you. I'm very bad at English and am using Google Translate for this whole thing... :D
Edit: You meant the options to switch to Win10/11 or Linux, kk :)
I have all of these OS, but I'm still looking for Windows 7 solutions :D

2. If I understand correctly, it's about the "zstd compression," which isn't natively integrated in Windows 7, but can be used with third-party software. For example, with 7z.

If this compression is included in Steam and the corresponding DLLs, why shouldn't it work in Windows 7?
- (By the way, I was able to update to the latest Steam version, June 30, 2025, with a launch parameter -no-cef-sandbox, which can be removed after the update, and Steam starts even without this command.)
- So, I'm looking for the dependencies on how Steam's query works, which DLLs are requested under Windows 10/11... There should definitely be a way to fix this?! Or not?

3. If the above is true, I don't quite understand why Steam didn't integrate its own support entirely? Because it would have been too complicated or would have cost more licenses than using the existing one in Windows 10/11? (<-I know, sometimes I'm great at answering questions right away xD)
