I created a workflow that copy the outputfiles on a distant server. I configured the workflow with an UNC path (distant server not the same as alteryx) and add access to the technical user : user1 who is the same user in the Run As.
This user1 could access the shared folder but when launching the workflow from the server i am getting this error : Cannot access the folder \\output\. (Tool Id: 5)
Where did you configure the "Run As" credentials? Keep in mind that the Server has separate credential management from Designer. Here's the documentation link for server "Run As":
