iOS Question Can't use Hosted Mac Builder

[GGSoft]

Until yesterday I was using Hosted Mac Builder as usual. Since today I can't. My device sends this message (image file attached). The translation into English is

-----
"Impossible download the app"
"<app name> can not be installed by now"
OK | Retry
-----

Am I the only one with this trouble?

Best regards.

Your certificate has probably expired. You need to create a new certificate and provision profile.

That was it.
Thank you very much.
