Hi all,

I'm having odd problems when making an https request in an smsbox service
(on latest compiled release from SVN and also Debian packages), I get back:

2024-05-17 15:14:25 [24] [9] ERROR: SSL write failed: OpenSSL error 1:
error:00000001:lib(0)::reason(1)
2024-05-17 15:14:25 [24] [9] ERROR: SSL error:0A000410:SSL routines::sslv3
alert handshake failure
2024-05-17 15:14:25 [24] [9] ERROR: SSL write failed: OpenSSL error 6:
error:00000006:lib(0)::reason(6)

It seems to be affecting only certain sites, i.e. ones I have behind
Cloudflare with an individual LetsEncrypt certificate (not a wildcard - but
wildcard LetsEncrypt sites break too).

I ran openssl s_client -connect and everything appears to be in order. When
I set up sms-service keywords to fetch Google, or the BBC News website,
everything works.

Does anyone have any ideas what might be causing this? Running kannel in a
docker container with debian:bookworm-slim as the base image.

Thanks
Alex
