Update to V8.8 no longer connects on existing profile on MacOS 12.0.1

Do you mean Core Tunnel 3.6?

I've sent you a premium license redeem code, so you can create more profiles, please check you personal messages.

When you create the profile, please also set Log Level to DEBUG3:

Then try again with the newly created profile, if it still fail to connect, please send me a copy of desensitized connection log.

Kindly Regards,

Yang
