Any image hosted on wikimedia.org gives an SSL error

Since yesterday I'm having trouble with anything related to the https://upload.wikimedia.org/ URLs, they all give an ERR_CERT_COMMON_NAME_INVALID error.

I tried some troubleshooting and I noticed that SSL Checker detects no errors ( https://www.sslshopper.com/ssl-checker.html#hostname=https://upload.wikimedia.org/ ) and even trying visiting the URLs with a proxy website like https://www.proxysite.com/ works.

I noticed that the certificate I get on my side looks suspicious to say the least ( https://i.stack.imgur.com/lKu8m.png )

This happens with every browser and even within the Windows 11 Sandbox Mode.

Could this be malware related? Please note that this is the only site I'm having trouble with, Wikipedia works fine, except all the images not showing being hosted on wikimedia.org Bimbo1989 (talk) 17:58, 28 November 2023 (UTC)

Bimbo1989 Since it seems like no one else is having this problem, it must be your computer. Check on another computer or smartphone to see if the problem is there too and check on your computer to see if an update is available. Killarnee (talk) 19:20, 2 December 2023 (UTC)
