cant ping any ipv6 addresses on router 2

[purpleshort]

Hey guys I'm a college student studying CCNA. I'm having troubles being able to ping any and all of my ipv6 addresses on router 2 from all end devices. I can ping all of router 1's ipv6 addresses from all end devices but not router 2. I have linked my packet tracer file, I'm rather confused on what is configured incorrectly.

Forgot my configurations were password protected. all passwords are P@ssword123

Hi @purpleshort ,

The .pkt file appears to be empty. Can you upload it again.
