ArcGIS On the web makes use of TLS to communicate with the rest of the ArcGIS Platform. Right now, it can use a handful of various versions (1., 1.1 and 1.2). But from February 2019, for safety causes, ArcGIS On the web will be updated so that it only supports TLS version 1.2 .
When this occurs, every client that communicates with ArcGIS On the web should also support TLS version 1.two. If they do not, functionality that makes use of ArcGIS On-line, such as the Living Atlas, Feature Solutions, Routing or Basemaps, will no longer work.
This page will guide you by way of the preparations you need to make on a solution-by-product basis. Not each and every solution requirements patching, but it’s essential to verify every little thing you use.
