There is also another unbound instance running on oort 8953, which is not default behavior?; ---

at least we changed from ```auto Sep 26 02:01:21 Pi-hole unbound[1074]: [1074:0] info: query response REC_LAME: recursive but not authoritative server Sep 26 02:01:21 Pi-hole unbound[1074]: [1074:0] info: mark as REC_LAME ``` to ```auto Sep 26 03:17:07 Pi-hole unbound[409]: [409:0] info: Capsforid: reply is equal. go to next fallback ``` Still unbound seems to have challanges with connecting to the root DNS server. 🤔 I guess `dig` is still failing? ```auto dig @127.0.0.1 -p 5335 google.com ``` ---

> [@xMike](#): > > ```auto > `;; ->>HEADER<<- opcode: QUERY, status: SERVFAIL, id: 32743` > > ``` That’s the important line as **status=SERVFAIL** It has something to do with the `Capsforid: timeouts` message on the log. I need to check where this is coming from. ---

let’s try to increase the log level once more. This should enable the debug mode. 🙄 ```auto G_CONFIG_INJECT ' verbosity:' ' verbosity:3' /etc/unbound/unbound.conf.d/dietpi.conf ``` Reboot the system and check the logs ```auto journalctl -u unbound.service ``` ---

sorry for digging around but I’m still not sure why Unbound has issues to connect to root DNS servers. Let’s try to increase debug level to the highest level 5. ```auto G_CONFIG_INJECT ' verbosity:' ' verbosity:5' /etc/unbound/unbound.conf.d/dietpi.conf ``` Reboot and check logs again ```auto journalctl -u unbound.service ``` and we could check the root DNS server directly if they are reachable ```auto dig @202.12.27.33 google.com ``` ---

Honestly I’m still not sure what the issue is exactly. There are quite some time outs on the debug log. Something seems to block communication betweem Unbound and root DNS server. Maybe @MichaIng or @trendy have an idea. For testing, we could try to adjust DNS forward zone to point to Cloudflare and Quad9. Let’s see if this might be working. At least we could check the general functionality. ```auto cat << '_EOF_' > /etc/unbound/unbound.conf.d/dietpi-forward.conf # Adding own forward-zone forward-zone: name: "." ## Cloudflare forward-addr: 1.1.1.1@53#cloudflare-dns.com forward-addr: 1.0.0.1@53#cloudflare-dns.com ## Quad9 forward-addr: 9.9.9.9@53#dns.quad9.net forward-addr: 149.112.112.112@53#dns.quad9.net _EOF_ ``` restart service and perform a test ```auto systemctl restart unbound dig @127.0.0.1 -p 5335 google.com ``` ---

worse comes to worse, might also try uninstalling the dietpi package…and manually install/configure (kinda defeats the purpose of using the easy to install package system though) I know when I put it on a debian 11 VM in PROXMOX on my network as a test…I followed this walkthru and it worked like a champ with NO issues…1st try [unbound - Pi-hole documentation](https://docs.pi-hole.net/guides/dns/unbound/) ---

ah, yeah. i actually installed it on a vps (ubuntu 20.04) earlier which worked fine with the same documentation, but for some reason i couldn’t get it to work with dietpi ---

> [@xMike](#): > > i actually installed it on a vps I guess the system was located outside of your network at a Cloud Server provider? Correct? This makes a difference as network environment is completely different. ---

correct! so it’s not a fair comparison for dietpi since there’s different variables at play [Previous page](https://dietpi.com/forum/t/unbound-not-working-with-pi-hole/14431.md?page=1) [Next page](https://dietpi.com/forum/t/unbound-not-working-with-pi-hole/14431.md?page=3)
