HELP!! Canon utility stopped recognising my cameras

[Memirsbrunnr]

Hello everybody. I have 2 bodies the 80D and 750D. I have been using EOS utility since i build this windows 10 PC (32 GB ram 8 GB video card, a few SSDs + HD, and a dedicated 4 GB HD for photo's) in April. Now in the beginning of September it suddenly stopped recognising BOTH my camera's, showing it is not a camera hardware problem. However, when I hook them up by cable windows 10 recognizes both cameras by name and allows to browse the flash ram cards.
So this shows there is some kind of software error with either windows 10 or the canon EOS utility. I have tried to connect the camera via WIFI same problem. No problem connecting the WIFI but the second step EOS utility will not see/recognise the camera.

Things I have tried to solve the problem:
1 I have downloaded the latest version of eos utility, and installed it. Does not work (2x)
2 I have called the danish telephone help-desk who could not help after a 20 minute discussion, but promised to forward it to their specialists. But they neither phoned or emailed me back.

Does anyone know if there are windows settings that have been changed by an update that need to be changed?
Did anyone have these kind of problems before and found a way to solve it?

I hope someone can help me with this because I am getting crazy with annoyance and my fun of shooting photo's is really suffering.

Are you using a VPN?

No, but as I indicated, I solved the problem by disabling EOS Webcam Utility services. It's a Canon software issue and I've reported it to them, along with the above solution.

I haven't tried the webcam software, but my camera won't connect to my phones with VPN. Unfortunately, while it is free with my service, a certain company's security software appears to force VPN.

I eventually found that EOS Utility sends SSDP broadcasts to port 1900 to find the cameras, but unfortunately EOS Webcam Utility also does. When the camera response comes back, EOS Webcam Utility receives it and not EOS Utility.

Wow. Thank you! This sounds like it will likely will solve my issues with it. My cameras stopped being detected by the utility over WiFi and now that I think about it this started when I installed the webcam utility. Canon support was worthless.
