I would like to confirm that the USG50 can also be configured (using CLI or web interface) to increase its minimum security level so that current Google Chrome is satisfied. Additionally, would this change impact any existing security definitions for VPNs?

    Chrome browser is most current release.

    VPN tunnels are using 3DES/SHA1, 3DES/MD5, AE2128/SHA1/ AES256/SHA1

    Looks like I don't have the  most current firmware BDS.9(C0) is available.

    I think the error being faced on Chrome appears due to a lack of “common SSL protocol version or cipher suite support” between a web server and a user’s browser. This issue happens during the TLS handshake process. To solve the issue, you can check out the following article:- https://certera.com/kb/how-to-fix-the-err_ssl_version_or_cipher_mismatch-error/.Error

    Maybe it will help solve the error.
