I am running 4POS ver 19.8.2. When I started the Backoffice today system told me it has to verify License, I must ensure that I have an Internet connection and restart backoffice. This I did, but it keeps telling me that I do not have an internet connection even though I have one, i.e. running Skype, am able to browse on google etc. There seems no way out. Any remedy for this.
