The Web Server App no longer working

I have two tombio keys currently in use by lots of people and have used the Web Server app for Chrome do develop/change the keys. This no longer seems to be working. Can someone help me to solve this problem?

Hello Mal. It looks like support for the Web Server app for Chrome is being ended this year - perhaps you’ve bumped up against that. The recommended way to run Identikit locally now is to use Node (with Electron) and it is explained here: tombiovis/ at master · FieldStudiesCouncil/tombiovis · GitHub
