QVRSurveillance 3.0.2.15888 breaks USB cam connections

I got a required update to QVRSurveillance 3.0.2.15888 and installed it.
Once I did my cameras no longer worked. There is a long standing bug that keeps coming up where it breaks with force HTTP to HTTPS connections enabled so you disable this, connect, then re-enable. However this time it did not fix it. I tried many other things, deleting the camera and attaching it and other things with no luck.

I found an old copy of 3.0.0.1485 and downgraded to that and it instantly fixed itself and connected on it’s own without any help from me, so this is definitely a problem in 3.0.2.15888 making it unusable.

Is this a known issue? Is there a fix? Will it be patched soon or will I be stuck with an older version?
And if anyone has a link to something newer than 3.0.0.1485 but older than 3.0.2.15888 I would appreciate it.

Hi @AnalogEngineer the previous version should be 3.0.1.1488

We will confirm the issue between version 3.0.2 and USBcam as soon as possible.
If you don’t mind using the beta version, I can provide you with a fixed version.

Thank you. I will try these later.
It was all working fine before 3.0.2 so I assume these will work,
If you wish me to test a beta then send it to me. I generally am only able to work on this NAS the later part of each week as I am off site other days.
