This is very little information to go on. See the troubleshooting page of the docs on how to get logs. Logging Bluetooth packets is really the only way to solve issues like this.

Based on the error message, I'm guessing you are using Windows. We've seen this error lots of time, so other issues that mention it may provide some insight. https://github.com/search?q=repo%3Ahbldh%2Fbleak+%22Could+not+get+GATT+services%3A+Unreachable%22&type=issues

If I'm remembering correctly, in most cases, this turned out to be a badly behaving peripheral or badly behaving Bluetooth adapter. Well, actually, in most cases, people didn't follow the advice to do a Bluetooth packet capture, so we don't know what it was.
