Changing the 'Automatically detect settings' option might make a difference. The ssl issues I encounter usually happen when connected to networks that perform ssl decryption. In my workplace they do this as well. We need to add certain root certificates for packet inspection; until you install the right ones, errors appear. The vulkan.lunarg.com certificate remains valid until the end of October, which means it was either refreshed or your browser isn't displaying it properly.
It didn't seem to make much difference turning on automatic settings detection or clearing caches. Deleting browser and Steam cache didn't help either. For websites, the launch command to ignore certificate errors worked only when accessing trusted sites, but Steam chat still didn't respond properly even after clearing related files.
I've tried restarting the PC, but the issue remains unchanged. The problem persists in both the browser and Steam.
Google believes there was a flaw during the transition from older Windows versions to version 20H2, possibly causing the certificate store to vanish. This issue typically impacts systems moving up from an older Windows 10 release, such as 1809, to 20H2. It has also been present since at least 1903 and 1909, lasting about a year before being addressed. The problem often arose when upgrading from an ISO made specifically for that purpose instead of using the standard Windows Update. While rare, it could also stem from a Windows Update itself. The recommended solution is to revert the feature update. Additional clues suggest an expired self-signed certificate was involved, which would have been removed or renewed with a new expiration date—check your certificate store for this.
Thanks for the research on this. The ISO version for this Windows setup was a fresh install of 20H2, as I recall. For updates, the ones applied on 30/09/21 are the ones you received earlier today. Would you know which version to revert to in order to resolve the problem? Spoiler: It’s worth checking that one.
Hello! I set up an account to address the same problem you mentioned. The Friends app wasn’t functioning properly, and I also encountered difficulties accessing the Steam store through the native app and Edge. Chrome was working fine. It turned out Steam certification was failing when fetching content from "store.akamai.steamstatic.com". I checked the certificates and noticed Akamai was using an expired one. I found a guide at https://valid-isrgrootx1.letsencrypt.org/ that shows how to obtain a valid certificate in Chrome, then copy it to a file. After saving it as a DER encoded binary, you can follow the steps on the provided site to import it into the trusted root store for Steam. Once done, restarting the app should resolve the issue. This method helped me, but results might differ.
When you don’t have the latest certificate, it should be added automatically while browsing. If your system is old—such as Windows 7—you may need to perform a manual installation.
