Create Solutions

We are on CRM PUM 16, moving to 19 in the next couple months. We are trying to create more dynamic solutions where there isn't a laundry list of attachments on a solution but the employee can click on a graphic that generates a hyperlink PDF. When we created the solution, we did internal PDF attachments which created a hyperlink. We added that hyperlink to the solution body where the graphic is. When we went into the solution, we receive this error:

Error 404--Not Found

From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:

10.4.5 404 Not Found

The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
