Forms SharePoint Online

Hello Team,

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

Dear @pkp,
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

Dear @pkp,
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.

Hello @Nikita_Kurguzov,

Please share the proxy URL Plumsail connecting to when it checks for license

Hello @Nikita_Kurguzov,

Please advise which proxy URL we need to whitelist since we are receiving Unable to check license error

Dear @pkp,
Make sure that the forms.plumsail.com is accessible
