I have been trying for days to figure this out. It happens only from this router
R1#ping google.com
Translating "google.com"...domain server (8.8.8.8) [OK]
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 2607:F8B0:4008:804::200E, timeout is 2 seconds:
% No valid source address for destination
Success rate is 0 percent (0/1)
R1#
If I ping the IPv4 address no problem I get the ipv4
If I change the DNS server no joy still error and ipv6
If I put behind another router that works fine with a private IP address still doesn't work
I reset router with erase startup-conf still not working
I defaulted the interfaces
I used no ipv6 unicast-routing still nothing
I have three routers that are on the same ISP and all work fine. This router will not respond and I cannot figure this out
Anyone that can help would be great! Thanks in advance

What interface connect this router to Internet?
Is name server and other DNS parameters configured correctly?
Can you post "sh run"?
