BOX cannot connect to server

I have been having multiple issues with BOX, Google Drive, and Dropbox lately as I know I have been targeted in an attack and do not know what to look for yet.  Could be they have put some code inside my BOX account/file storage and that is why but I do not know.  I know these people have downloaded "self-signed" certificates from Godaddy and other certificate authorities inside my MAC/Windows 10 machines and at the router level, as well.  Any help would be greatly appreciated.
