Suddenly unable to subscribe to notifications from and write to characteristic

[ahSOLO]

Hi, thanks so much for putting together this package, it's been very helpful for one of my projects. A few days ago I was able to get everything communicating nicely between my Arduino board and Windows PC, but today I suddenly encountered the following errors when trying to subscribe to notifications or write to a characteristic:

Here are some more details:

• I've tried rolling back my code without success, and my previous builds are no longer working. I even tried rolling back the most recent Windows updates without success.
• The same errors are occurring when I try to subscribe/write to the device from Microsoft's BLE sample, and from your demo scene.
• The errors are reproduced on multiple PCs, and I also get the same errors using third party apps on my PC such as this one .
• I am experiencing the same errors when trying to communicate with a second BLE device (that I had no trouble communicating with before today).
• I'm able to scan for the services and characteristic UUIDs from the device, I just can't subscribe to or write to them.
• Everything works when I try to subscribe/write to the devices using an android phone, or macOS laptop.

Would really appreciate any hints on where to look for a solution!

Turned out it was an internal company policy that blocked BLE communications, closing this issue.
