Can't connect to Steam servers and other gaming servers on Windows 10
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 I even tried replacing my router, as it was a bit out of date.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.

Why can I not connect to Steam servers?
As Steam could not connect to its servers, the problem may be caused by your antivirus/Firewall that could be blocking the communication between Steam and its servers. In that case, disable your antivirus or turn off your Firewall. These applications usually block access to Steam's servers because of a false positive.CAN - Paperhouse (1971)
