Hi,

I get ERR_SSL_VERSION_OR_CIPHER_MISMATCH for example on https://www.ssllabs.com.
(GET https://www.ssllabs.com/images/main-background.jpg net::ERR_SSL_VERSION_OR_CIPHER_MISMATCH)
Desktop Chrome don't have issues, I reset SSL, Clear all cache nothing helps.
Currently only my machine in a Hyper V has this problem (Windows 10, all patches).
I use the 32 bit Version of CEF4Delphi.
Do you need other informations?

Hi,

What CEF4Delphi version are you using?
Post what you see when you load chrome://version in your browser.

I just installed that version of CEF4Delphi
https://github.com/salvadordf/CEF4Delph ... 0.4240.198

I loaded the URL you mentioned with the SimpleBrowser demo in 32 bits.
https://www.ssllabs.com/images/main-background.jpg

I use Delphi 10.4.1 on Windows 10 Pro (64 bits), version 20H2 (19042.630) and I didn't get that error. It loaded the image correctly.

Are you using any kind of proxy server?

No nothing more than the Network from Hyper-V.
On my host it works, only in the virtual machine it seems to have problems but I cant figure out why.

I also tried it on a VirtualBox machine and it works fine.

This looks like an issue in the network emulation of Hyper-V.

The strangest thing is sometimes it works and after several reloads its gone... I think I will observe this and search for more clues.
