Enable TLS 1.3 only on GCP Global Ext App LB. Reject clients connection using TLS 1.2 or lower

[azzi]

Hi guys,

In GCP Load Balancer there were SSL Policy settings. In there, we can set the minimum TLS up until 1.2 only but not 1.3

I have tried to create custom profile by selecting only below ciphers that exclusively designed for TLS 1.3 but failed

Any ideas?

Thanks
