I have Xeoma Standard installed in an Ubuntu 20.04 LTS server with 4 cameras. I've just recently updated Xeoma to version 24.2.14 from 23.8.10.
If I connect from my android phone, everything works smoothly, but if I connect from my Lenovo T480s laptop running Linux Mint 20, I get "Waiting for image from camera ..." for about 40 to 60 seconds, before getting the actual images. I went back to 23.8.10 in my laptop and cameras work correctly, I get the images as soon as Xeoma starts (I get a complaint about the version, but it still works).
So it seems that someting is wrong in the Linux 64bits 24.2.14 version of Xeoma or maybe there is a setting that has changed and I need to do something to fix it.
