If you read the error message, you will see that on line 734 of the attached toml file cache_file = 'odoh-relays.md' is defined inside the [sources] table (line 704), and you will also see that on line 728 cache_file = 'odoh-servers.md' is already defined inside the [sources] table. Clearly you meant to comment these (and other) lines, or meant to uncomment lines 726 and 732.

TOML syntax for duplicate keys is specified as follows: "Defining a key multiple times is invalid." I don't think it appropriate for dnscrypt-proxy to "work normally" in the face of configuration syntax errors.

dNS relays

Ni, i dont think so.

Goto 704, i have commentd out public resolvers sources and anonymised DNs relays. Thats all commented out.

The only one being used is the ODoH servers section - thats not commented. So sources are only once defined in the ODoH section, rest is all commented out.

Dont close the thread, it not resolved as yet. Thankyou
