"Unable to retrieve a snapshot" for just one camera

### Homebridge Platform and OS

### Describe the problem

I'm not totally sure exactly when this issue started or what could have caused it, but the plugin was working flawlessly until a couple of weeks ago. I have 5 different cameras connected and only one of them recently started not updating its snapshot in the Home app, but if I try to livestream everything works correctly.

It is worth noting that I only just updated the node version because I thought it could help solving my issue but I actually was on v18 (sorry, don't remember exactly which subversion and I totally forgot to write it down).

The cameras and the Raspberry Pi running HB are on two separate VLANs but I know that the firewall rules have been set up correctly and that every device is on the proper subnet etc.

Thank you for your attention!
