Steam – Can’t connect to Steam servers and other gaming servers on Windows 10

networkingsteamwar-thunder

I have been having an issue with Steam. Whenever I try to log into it, it tells me that it is having trouble connecting to the Steam servers, and won't let me log in. I used to be able to use Steam perfectly fine, but I started getting issues after I moved.

I have tried re-installing, deleting ClientRegistry.blob, and everything else. I even tried replacing my router, as it was a bit out of date. Despite all of these, none of them have helped.

I am also having issues connecting to the Warthunder servers outside of Steam. It says I have limited Ethernet, but I am able to use the internet on my computer. Another thing that is not working are .io websites. I am unable to connect to them.

Despite these things, I am able to use the browser version of steam.

Your ISP is likely transitioning to IPv6 using "IPv6 Dual-Stack Lite" or similar. In this method:

When a user’s device sends an IPv4 packet to an external destination, DS-Lite encapsulates the IPv4 packet in an IPv6 packet for transport into the provider network. Tunneling IPv4 over IPv6 is simpler than translation and eliminates performance and redundancy concerns.

Other Steam users have reported similar problems (thus my assumption): https://superuser.com/questions/1051632/translating-ipv6-packets-to-ipv4-packets-to-reach-a-game-server

Solutions:

Confirm with your ISP that they are in fact using an IPv6 Dual Stack Lite configuration
ask your ISP for a proper IPv4 address
or, try the instructions from that link. They look a bit more complicated than talking to your ISP though.

Steam – How to disable Steam from starting up with Windows without logging in to Steam

If you want to do this without starting Steam and logging in, you can modify the setting in the Windows registry. The autostart checkbox is directly tied to a registry key — simply deleting it is all the Steam client does when said checkbox is unchecked.

Navigate to HKCU\Software\Microsoft\Windows\CurrentVersion\Run and delete the Steam key. Or as a .reg file:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run]
"Steam"=-

Steam – Using the Steam overlay to play music/other normal browser things

As the Steam browser doesn't come with a copy of Flash, it will need to be installed manually - this can be done by following these instructions from the Steam website in your normal web browser (ie: Google Chrome/Firefox/Safari/IE).

Navigate to the Adobe Flash website for "Other Versions"
Select your operating system, for example "Windows 7/Vista/XP/2008/2003"
Select "Flash Player for Other Browsers" from the second drop down
Click the "Download Now" button to begin the download
Install Flash for Other Browsers
Once the installation has completed, you will need to restart Steam in order for the plugin installation to take effect

After following through the above steps, I was able to watch videos on YouTube. I wasn't able to test Pandora Radio as it is not available in my region but so long as it is Flash based the above should allow it to work.

Regarding HTML5 support in the Steam browser, this should be supported - the Steam browser is based off Webkit which does support HTML5. To help validate what the issue is in relation to your ability to load HTML5 content within the overlay, browse to the YouTube HTML5 status page;

This will give you an information page which includes a small checker at the bottom which will confirm your compatibility with the HTML5 video tag, h.264 codec, and WebM;

To enable WebM/h264 compatibility in the Steam Overlay you must use the beta version of Steam as per this thread.
