Vortex - "invalid" SSL Certificate - SSL Proxy

[fxhome]

Hey,

I got an issue with the Vortex Client behind SSL Proxy. I already excluded decryption for Nexusmods and can login and download stuff via Vortex.
But as of today, I cannot download big files (like the one in the picture). It was possible before and there were no changes from my end, small files are also possible to download, but if I try a bigger file, Vortex starts giving me the error.

I'm using the newest Vortex Client 1.10.8

I already logged out of the client and installed the same version on top.

Any help is appreciated.

 

EDIT: Is it possible to see the chain Vortex is referring to somewhere?

This is almost always caused by local security apps interfering with normal certificates. Either than or you need to install the latest Windows Updates on your PC.
