Thank you for the answer @miconda
I tried to fix in similar way and modified /etc/ssl/openssl.cnf like they did. [openssl_init] providers = provider_sect
[provider_sect] default = default_sect
But. As the result i see errors like this: systemctl restart kamailio systemctl status kamailio
kamailio[5569]: CRITICAL: <core> [core/pass_fd.c:281]: receive_fd(): EOF on 71 kamailio[5569]: CRITICAL: <core> [core/pass_fd.c:281]: receive_fd(): EOF on 55 kamailio[5569]: CRITICAL: <core> [core/pass_fd.c:281]: receive_fd(): EOF on 46
Kamailio begins to work again in case i rollback changes in openssl.cnf
Please advice
