> When modern openssl is used (i.e  OpenSSL 1.1.1f, which is default for ubuntu 
> 20.04, for example),  provided certificates are not accepted, because 
> Sha1WithRSAEncryption signature is used, that is widely considered flaw. So 
> certificates needs to be renewed (i.e. with sha256WithRSAEncryption signature)
> Example error:
> {code}
> Connecting to 127.0.0.1:11110

> weak:../ssl/ssl_rsa.c:310:
