Title: [SOLVED] ssl handshake errors between unbound and DNSoverTLS enabled forwarders
Post by: rookie on March 07, 2019, 08:10:15 PM
I upgraded my firewall from 18.7.10 to 19.1.2. Now I have an issue with unbound and forwarders via DNSoverTLS.
Unbound starts and is listening on all ips but doesn't resolv any requested names. The unbound log has entries like this:

[1551968079] unbound[33902:1] debug: iterator[module 1] operate: extstate:module_state_initial event:module_event_pass

[1551968079] unbound[33902:1] debug: iterator[module 1] operate: extstate:module_wait_reply event:module_event_noreply

The happens with flavour default and OpenSSL. I didn't try LibreSSL, because I had problems with it under FreeBSD in the past and switched back to OpenSSL.

I reinstalled the ca_root_nss package without luck.

Any ideas how can I solve this issue?

Code Select
[1551968079] unbound[33902:1] error: ssl handshake failed crypto error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed                                                                                                              Failure to verify certs could be indicative of time being improperly set. Add 1.1.1.1 as a system dns resolver and make sure you can sync NTP clock first

Thanks for your answer but it didn't help. The system clock is in sync.

I found a solution for my issue. I added following line to a server block and afterwards the name resolution works.

Code Select

tls-cert-bundle: /etc/ssl/cert.pem
