Hi All,
My fix for the Personas issue with the error message "A problem with the network connectivity has been detected".......
Found SAP Note 2016378 had not been applied correctly via SNOTE. Originally the "Copy Changes" (see below screenshot) was left unticked. Fixed issue by re-implementing the note with all boxes ticked - issue now solved.
I hope this helps with anybody else who has this issue.
Cheers, Claudio.
