Another IPv6 weirdness with ISP

What issues?
I knew I'd miss something.
IPv4 tests are OK. Any other test will time out after 15 seconds.
Opening one of the idividual tests in it's own tab will time out. -
Sounds like you don't have IPv6. When you go to ipv6.google.com, are you able to do anything?

they can look up IPv6 DNS (pi-hole server
via GUA or some link local address? You can look up a IPv6 address ie AAAA over IPv4..

If I go to test-ipv6.com, it reports issues
Ok, you didn't saw this one :

Help?!
Help offered - I'm also with iDNet (good idea going with a quality ISP over a cheap one) so can offer any settings you need.

The physical WAN link (to my ONT) - Don't miss the 1508 MTU setting for PPPoE overhead:
Main LAN configuration:
Hope these help - if not just ask.

@Gertjan You're right - I'd love to see those!
This is what I get:
If I I try one of the URLs which times out (e.g. the vm3 link) as an individual page, it still times out:
If I try a test-netconnection on port 443, it's OK:

@JKnott I get the usual Google page with ipv6.google.com. If I ask it what my IP is, it responds:
If I go to ifconfig.co, it tells me the same:

@RobbieTT
OMG - it was in there!
You're using FTTP (I think), but your point about MTU got me thinking....
The WAN was set to 1492 by the ISP. The LAN defaulted to 1500. I changed this to 1492 et voila!THANK YOU SO MUCH!
@JKnott @johnpoz @Gertjan Thank you for jumping in and helping. It was the MTU size which was killing packets... I finally got there!

No problem at all. It does not matter if you are on FTTP or not, the physical link on the WAN to your ADSL/VDSL2/G.fast modem should be 1508 MTU, allowing a normal 1500 MTU to traverse wearing the 8-byte PPPoE wrapper (ie as per my settings).
