SSTP server gives 400 bad request

[david-hoze]

Hi, great work!

I'm using sstp-client to connect to an accel-ppp server I'm running. The server, after getting the CLIENT HELLO message, sends 400 bad request, Unencrypted HTTP protocol detected over encrypted port, could indicate a dangerous misconfiguration. to the client.

What am I doing wrong?

you have not configured sstp section, so ssl is not working.

[david-hoze]

Thanks for your reply :)
Can you give me a simple example of sstp configuration or a link to a simple walkthrough? I haven't found one unfortunately..

[DmitriyEshenko]

Hello, maybe manual helps to you man accel-ppp.conf or you can use web version https://accel-ppp.org/accel-ppp.conf.html#lbAP

[david-hoze]

Yes, I configured it and it works now, thanks!
