Hi! Welcome to our forums.

This is the line where your error is coming from:

I really can’t tell why the test was ok but it now gives this error.

One wild guess it comes to my mind is:

Have you restarted the server after the federation configuration? Not that is necessary, but I have seen some configurations only taking effect after a server restart.

Also, can you confirm you can resolve the DNS name of the server from onde peer to another?

Hi and thanks for your help. I`ve Done your suggestions and here the result:

my first server domain is xxxx.com and another is chat.xxxx.xxxx.us
I tested the DNS from xxxx.com server and the result is:

dig srv _rocketchat._https.chat.xxxx.xxxx.us

DiG 9.16.1-Ubuntu <<>> srv _rocketchat._https.chat.xxxx.xxxx.us
Got answer:

this is the SRV record. and here is TXT record:

DiG 9.16.1-Ubuntu <<>> txt rocketchat-public-key.chat.xxxx.xxxx.us
