today we encounter a problem while implementing a workflow on SharePoint 2013 with IE 11 (Version 11.0.75 on Win 7 and Version 11.0.80 on Win 10).
If we add the "Call Web Service" Action and try to instantiate e.g. the lists.asmx we receive an error "Service unavailable"
On one of the servers I had an old version of IE 11 Version 11.0.60 - with this version the action is working without any problems.
With Google Chrome the action is working without any issues
Did anybody encounter the same issues or has an idea how to fix that?
