Google Trust Services dns-01 issue

[mhmtyylc]

Google Trust Services dns-01 verification method constantly says invalid as an answer and cannot verify. I would be glad if you could check it.

It seems to work fine (just tested it):

Maybe it takes some time for the DNS-Record to become active on the authoritative name server(s).

Does it help if you use a delay like this?:

$handler=function($opts) use ($ac){
  switch($opts['config']['challenge']){
    case 'dns-01':
      
      // set dns record here
			
      sleep(120); // wait some time to allow the dns server(s) to update
			
      return function($opts){
        // remove dns record here
      };
    break;
  }
};

Does it say something like "Challenge validation failed: The TXT record retrieved from xxxxx at the time the challenge was validated did not contain..." (urn:ietf:params:acme:error:incorrectResponse) or is it another message/error?

It says "Challenge validation failed: The TXT record retrieved from xxxxx at the time the challenge was validated did not contain..."

And using a delay does not help?

Delay fixed the problem. Thank you very much.
