I can successfully access Plumsail Forms designer for SharePoint and can select a list as well
However once a list is selected I am getting error message 'Unable to check a license, please try again later. The remote server returned an error: (407) Proxy Authentication Required
But no URL mentioned. Please advise which proxy it is trying to connect
Have you followed the installation instruction fully? You need to make sure that the SharePoint domain is added to the Plumsail Account.
Yes. I can work on dashboard designer successfully. Plumsail set up was working for me before. I am using 1.8.7 version
What do you mean by Dashboard Designer? It's a different app, with different installation instruction, please, follow this one step by step to make the app work - Installation of Plumsail Forms for SP Online (Office 365) — SharePoint forms
Make sure you've added your domain to the Plumsail Account:
Hello @Nikita_Kurguzov , thank you for the update!
It seems like proxy issue since the same forms designer works on another machine.
Please share the proxy URL Plumsail connecting to when it checks for license
Please advise which proxy URL we need to whitelist since we are receiving Unable to check license error
Make sure that the forms.plumsail.com is accessible
