TP-Link Archer BE550 IPv6 Configuration

I utilize TurkNet internet services; I activated my IPv6 subscription some time ago. I recently acquired a TP-Link Archer BE550 router and currently have working IPv4 internet access. However, I'm struggling to establish an IPv6 connection. I would appreciate assistance from experienced users.


I contacted TurkNet support; they informed me that the IPv6 service had been deactivated last month.
