Gateway Locations DNS over TLS errors

Zero Trust Gateway
#1

Hello.

Apologies for my English - I’m use a translator.
I,m new on this platform.

After entering into my router, the data from the Gateway->Locations panel

172.64.36.1
172.64.36.2
xxx.cloudflare-gateway.com

I get the following errors

notice: ssl handshake failed 172.64.36.1 port 853 error: ssl handshake failed crypto error:1416F086:SSL routines:tls_process_server_certificate:certificate verify failed

Best regards
Tomas

Remove the IP address entries. They won’t validate for DOT

Thank you for your quick response.

The page you provided I read earlier.

In my case, the IP address and TLS Hostname fields are required in the router settings - IPFire.

Below is the content of the forward.conf file:

forward-zone:
	name: "."
	forward-tls-upstream: yes
	forward-addr: [email protected]#xxx.cloudflare-gateway.com
	forward-addr: [email protected]#xxx.cloudflare-gateway.com

An additional error is “Reverse lookup failed”.

If I use 1.1.1 instead of the Location Panel data, the errors do not occur.

PS. I cannot upload and paste graphic attachments and edit my posts :confused:
