For some reason, when they reopen their projects after closing they often lose connection to one or more of the layers (seems pretty random). Has anyone experienced this before? Interestingly, they can't reconnect to the service using the repair data source menu, it gives an error. They&nbsp;instead have to pull in a fresh copy from the Portal. We just upgraded our Enterprise deployment last month and republished all these layers.&nbsp;</P><P>Thanks,</P><P>Elliott</P> Thu, 21 Oct 2021 00:03:31 GMT https://community.esri.com/t5/arcgis-pro-questions/portal-layer-connections-breaking-randomly/m-p/1109505#M46957 EBaker 2021-10-21T00:03:31Z https://community.esri.com/t5/arcgis-pro-questions/portal-layer-connections-breaking-randomly/m-p/1109663#M46972 <P><a href="https://community.esri.com/t5/user/viewprofilepage/user-id/467385">@EBaker</a>&nbsp;</P><P>What error do they receive when they try to repair the data source?</P> Thu, 21 Oct 2021 12:58:46 GMT https://community.esri.com/t5/arcgis-pro-questions/portal-layer-connections-breaking-randomly/m-p/1109663#M46972 ABishop 2021-10-21T12:58:46Z
