[BUG] ServerFailure multiple domains with 11.5 release #764

Closed brokoler closed 8 months ago

brokoler commented 8 months ago

Hello,

I just happily updated to 11.5 and discovered issues on my end devices. For example my iPhone told me it's offline now, I did not have any issues with 11.4.1

I checked my server logs and see following: grafik grafik

Many more domains are affected, the screenshots above show the issue for my iPhone telling me it's offline.

Could this be fixed rather soon? I will downgrade for now.

Kind regards

Confirming the issue is gone after downgrading to 11.4.1. I will stay with 11.4.1 for now.

I have changed from DNS over TCP to DNS over UDP and that is working now.

scott-feier commented 8 months ago

Similar for me. I had DNS over TLS setup to Quad9 Secure, and was getting a ton of errors. Changed to DNS over UDP and issues disappeared. Here's a typical log entry:

I am also getting this same error. How do I downgrade to the previous v11.4.1?

Having the same issue on DNS over TLS, changing to DNS over HTTPS solved it for me.

ShreyasZare commented 8 months ago

Thanks for reporting this issue. It an issue only with DNS-over-TLS so switching to another protocol will help mitigate the issue meanwhile. An update for the bug fix will be made available very soon.

ShreyasZare commented 8 months ago

Technitium DNS Server v11.5.1 is now available that fixes this issue. Do update and confirm.
