Not getting v6 anymore?

I've been getting IPv6 for like the 12 years I've been a comcast customer, and, for the past ~5ish years that i've had a Mikrotik router I've been able to get v6 but it recently stopped working. (Not 100% sure when, only noticed today when trying to test connectivity to a GUA v6 address.)

[admin@router.vp] /ipv6/dhcp-client> export terse

/ipv6 dhcp-client add add-default-route=yes interface=ether1 pool-name=comcast-ipv6 pool-prefix-length=64 prefix-hint=::/60 request=address,prefix use-peer-dns=no
[admin@router.vp] /ipv6/dhcp-client> print

# INTERFACE  STATUS        REQUEST
0 ether1     searching...  address
                           prefix

Anyone have any idea?
