Steam - Unknown Error 1:86001S:51009S:11468332130:1073807360Q

I've been getting this error for days. I tried every possible solution, changing the NAT, DNS, clearing the cache, unlinking and relinking the account, and even formatting the PC and keeping only Battlefield installed, but the error kept happening every 10 minutes.

I saw someone on Reddit suggesting to download Cloudflare WARP, an app that optimizes your network route, and I’ve been error-free for a whole day now. It might be a temporary fix, but give it a try.
