When we attempt to login to 2 separate USG100 devices with latest version of Google Chrome we get the following error: This site can’t provide a secure connection 192.168.1.1 uses an unsupported protocol. ERR_SSL_VERSION_OR_CIPHER_MISMATCHHide detailsUnsupported protocolThe client and server don't support a common SSL protocol version or cipher suite. Followed suggestions detailed here however no difference, same error: https://community.zyxel.com/en/discussion/1920/attempt-to-login-to-usg40-chrome-reports-err-ssl-version-or-cipher-mismatch Curious thing is we can access a USG20W using same browser Chrome from same workstation (Win11 Pro) and no errors - so identical Internet Options, Chrome settings, etc. We believe it must be a different setting on the USG40W compared to USG100 causing this. Anyone have any ideas?
