[Pkg-openssl-devel] Bug#871918: libssl1.1: tls_process_server_hello:unsupported protocol

[Christophe Troestler]

Package: libssl1.1
Severity: grave

Dear Maintainer,

After installing version 1.1.0f-4 of libssl1.1 (and openssl), fetchmail 
started to report errors such as

fetchmail: OpenSSL reported: error:14171102:SSL 
routines:tls_process_server_hello:unsupported protocol

and mbsync also started to fail with

Socket error: secure connect to outlook.office365.com 
([2603:1026:205:14::2]:993): error:141640BF:SSL 
routines:tls_construct_client_hello:no protocols available

I had to downgrade to continue being able to fetch my mail!

Best,
C.
