if I try to connect to the server autoconfig.thunderbird.net with HTTPS, it failed with the error "Unsupported server key exchange hash algorithm" in the debug log.
example URL: https://autoconfig.thunderbird.net/v1.1/wanadoo.fr
Language: Visual C++ 10.0 (32-bit)
If you need the verbose debug log I can send it to you. Please let me know.
This new build should fix the problem:
It is the pre-release to v18.104.22.168, which will be released very soon.
