TL-WPA7510KIT V2. wifi setup missing in tpPLC utility / no web access using tplinkplc.net
I used to be able to setup the wifi on the 7510 (change SSID and password) succesfully using the web interface. Recently switched internet provider and have now a new router with builtin DHCP server providing IP addresses 192.168.1.x
Would like to change the SSID and password for new use. Recently downloaded the tpPLC utility V1.2.3909.1 (I have macOS 11.6.2). It shows the extenders (8E64 is the 7510) but the wifi settings are not available:
The online help suggest to use the web interface, however web access via http://tplinkpc.net gives a page with the "It looks like you may have run into an issue" message.
I have my MacBook Pro only connected to the wifi provided by the 7510 (which is a different SSID as the one from the internet wifi router), my setup is as depicted in the picture below, I have internet connectivity:
Using terminal I ran:
$ nslookup
> tplinkplc.net
Server: 2001:568:ff09:10c::68
Address: 2001:568:ff09:10c::68#53
Non-authoritative answer:

What am I missing to get access to wifi settings?
