I am getting ipv6 in router and ipv6 test sites were working. I could also ping ipv6 few days ago.

But now all ipv6 test sites fail to detect, in router i can see ipv6 is assigned.

Don't know what is the issue all settings are same.

Edit:

Somehow ipv6 started working on lan after enabling Ula prefix in router

Are you getting a single ipv6 (/128) ip on router or are you getting a whole subnet (/64 or /48) on your router for all your devices having different ipv6 addresses.

/64 on router

Any helpful guide on how to set up ipv6 for TP-Link router? Anything i need to change from below settings im using right now?
I'm using type PPPoE
Get ipv6 auto
Prefix delegation enable
In lan assigned type SLAAC+Stateless DHCP

Try lan assigned to dhcpv6

Just tick the enable ipv6 option - Dynamic - DHCPv6
In LAN settings - RADVD - ULA prefix(optional)

Try lan assigned to dhcpv6

This option works too but seems like im not getting ipv6 on my wifi connected devices

Dynamic doesnt work for me only PPPoE (same session with ipv4)
