SharePoint configuration issues in Nav 2017

allanero

Hi.

I have a problem in Nav 2017 in standard SharePoint connection settings.

I configured it a few years ago with my SharePoint site and it had never given me problems, but for a few months, just by hitting the Test connection button, I get the following error:

Could not connect to the SharePoint site. SharePoint Server returned the following error: Could not connect to the following SharePoint site: 'xxxxxxxx'. SharePoint Server returned the following error: 'Connection ended: Unexpected send failed.' ..

Does anyone know what could have happened or if I have touched something without realizing it?

Greetings and thanks.
