Desde que a MEO passou a disponibilizar IPV6, que tenho problemas ao aceder a bastantes sites https, com o erro:
"This Site cannot be reached. ERR_CONNECTION_RESET"
Basicamente é isto: https://github.com/pypa/pip/issues/5374
Se desactivar o IPV6, tudo passa a funcionar.
Aqui está uma possível explicação para o problema, tirada da issue do GitHub que coloquei em cima:
There is a known issue with Thomson / Technicolor Gateway routers where they reset the IPv6 flow label in the middle of a TCP session when it is supposed to be static from the SYN to the FIN.
Large networks and service providers, Fastly included, use ECMP for load balancing. Ideally the path selection uses hashing that keeps a single TCP session on the same path.
Although Fastly mostly avoids using IPv6 flow label as an input into hashing:By reseting the IPv6 flow label in the middle of the TCP session the router is likely forcing ECMP rehashing somewhere in the path between yourself and Fastly. This could mean that subsequent packets land on the wrong cache or even in the wrong POP.
- some equipment does not let you exclude it
- some other networks choose to configure it.
You can prove it's the router by connecting your computer directly to the ONT and retesting.
I don't have any straightforward solution for you. Your options appear to be:
- seek out the latest firmware for your device, see if that fixes the problem
- replace the supplied router with one of your own
Disactivar o IPV6 não é solução a médio prazo, por isso agradeço uma solução definitiva.
E porque não. oferecer um router novo a todos os clientes para substituir o velhinho THOMSON TG784n?
Obrigado.
