Security Certificate Error

I read over the other threads and they do not seem to apply to this. 
We have 6 computers using them at a school.  When we open tinkercad we get the security certificate Error.  None of them can edit the files.  We can open them but not edit or load them.  WE get a 404 file not found error.   Please help.  Children are in a 3d printing camp for only this week.

It works when we use our phone as a hot spot but not with the internet from the school
