InfoPath Dev

From few days, when I try to save and publish a form, I get this error:

InfoPath can not connect to the server. The server may be offline, your computer may not be connected to the network or InfoPath Forms Services may not be enabled on the server. To solve the problem, check the network connection and then try again.

the strange thing is that until a few days ago everything worked: I could modify the form and publish it.
I checked the data connection. all ok.
InfoPath Forms Services is ok.
I repeat, until a few days ago everything worked.
it is possible that you have changed the permissions on sharepoint? if yes, how can I check it?

 Thanks in advance for you support.

Hello pcetrone,

Another thing to check would be the design checker. Sometimes there may be an error in your form that is preventing the publish.

At times SharePoint also times out in the connection to your local desktop. As a work around, I will often login to SharePoint, and download the latest published template from the library to force my local desktop to open the connection to SharePoint, and then immediately publish the new version.

Hope that helps!
