fortigate Capitave portal Issue

[MahmoudH93]

when configured captive portal some sites didn't work  with error :
err1 - ERR_QUIC_PROTOCOL_ERROR
err2 - ERR_SSL_VERSION_OR_CIPHER_MISMATCH

like : YouTube , google , LinkedIn  and google search

else some sites works normally and redirect to captive portal AUTH page .

when I remove or authenticate all sites works normally 

I try it with (chrome , brave and IE browsers) 

(version 7.0.9 VM)
