Hi @sim3vi
You could take a reference at the links below which discussed the similar error:
Federation Information could not be received
Federated Sharing Setup Issues
Check if the question is related to TLS 1.2 enabled or Autodiscover configuration?
Run:
Get-FederationInformation -DomainName <yourdomain.com> -verbose
it may take a while to complete
The command give me a result such Federation information could not be received from the external organization.
I think there are some problem to onprem sharing. It'right?
If I try with mydomain the error is Federation information could not be received from the external organization. If I try mydomainonmicrosoft works.
