Port is already used error #57368
My Eqod mount just started doing this out of the blue. Had connected without issue before.

If I just unplug it, plug it back in, then restart Ekos - it works. Any idea what causes this?

Thanks

Port is already used error #57372
I experience this error as both a result of the semi-random order that the tabs start up (thus devices start up), and as a result of not using the port mapper. Jasem has a video on mapping ports to named devices that would likely solve this for you. I'm just too lazy to do it. It's pretty easy to just scan the ports if necessary at startup contention and set another available port. But I believe the youtube video gives details on how this is done to avoid it entirely. Cheers, Doug

I experienced the same problem recently. Usually it is the mount that cannot connect. All I have to do then is click 'Connect' in the Control Panel and the problem usually goes away.
The other option is the port mapping. After it happened for the third time, that's what I did and it seems stable since then.
