Delay by connecting about Domain

Hello together,

i hosted a teamspeak-server on my little raspberry 4b and everything works great,
the onliest “problem” is the delay if you connect to this server.
If sombody connect there will be a delay of 3-4 seconds before joining.
If i connect to some other teamspeak servers, i get connected within 1 second.
A connection about the IP, without resolving DNS works fast and does not surprise me.

Im not sure where the problem is, i get a free .tk domain and set in cloudflare an A-Record and SRV-Record which works correctly.

Could the problem be, that my TS-Server ties to resolve TSDNS at first?
I dont use TSDNS and im not sure why i get this message in the Client-Log:
“TSDNs Info TSDNS queried unsuccessfully”.
“TSDNS Info No TSDNS found”
Could the problem be there?
