I just tried Factory reset, then installing the latest firmware (again), on top of the MFG tool clear.
Testing it, I notice something strange: Of all,
https://google/com actually works. Now, I don't know whether Google has some function where it default 'down' to a lesser encryption if the browser cannot handle the higher version. From the details below, I very much suspect it.
All other SSL sites I have tried, fails.
Encryption level (as reported from a PC with Pale Moon on Linux).
This works:
https://google.com - AES128-GCM, 128 bit keys
These fail:
https://webmail.hosts.co.uk/ - RC4, 128 bit keys
https://startpage.com/ - AES256-GCM, 256 bit keys
https://duckduckgo.com/ - AES256-GCM, 256 bit keys
https://firstlook.org/theintercept/ - AES128-GCM, 128 bit keys
https://www.techdirt.com/ - AES128-GCM, 128 bit keys
As you can see from the last two, same encryption as Google.
I am at a complete loss...
Any ideas are most welcome!
Cheers!
