Dahua 5449T1P-ASE-D2_3.6mm suddenly fails to connect to Blue Iris

[Cooltiger]

This camera worked happily for several months now fails to connect to Blue Iris.
I have done the following.
New cable
Swapped POE switch (other cameras are working on the switch)
Rebooted BI server
Changed BI version between stable and latest
I had not touched anything on the day of failure!
I can still log in to the camera via explorer and ISpy but BI reports No Signal and Failed to connect

Has anyone got any ideas?

did you try to discover the camera again

Good idea Coldair. I rediscovered and got the camera back. Will see if it is still there in the morning. Many thanks.

No luck. Camera disconnected this morning. Discovery started it again. Still stable oniSpy . Very strange.

If that camera doesn't have audio, be sure to disable the audio in bI for that cam.
Be sure to read the version update notes in the BI helpfile.

I had the camera audio disabled in BI, but enabled in the camera settings. I disabled this setting and will see how it goes. As per Murphy's Law this is my only really hard to get to camera mounted 20 feet high.
This BI runs on W11 and I update BI regularly with no problems.
I have another remote system on Server19 and only run stable BI, with no problems.
I am setting up a third BI on Server22.
I have 2 Dell SFF 7040s and one SFF 7070.
I have to run AI on all cameras as spiders cause havoc at night time. Tiny spiders walk across the lens and large spider try to wrap the cameras up. I live in a spider rich environment

This is a Golden Orb Spider that lives near some of my cameras

One of these come to mind.

Problem fixed

After trying the above suggestions with no luck I took the camera completly off BI and then reconnected it with a new IP . It has now been solid for 4 days.
