Hi @jur_osinga thanks for letting us know that this has been happening, we’re sorry for the delay in our reply!
@MamaTried has some great points, this can usually occur when network issues are present. So that we can properly assist, could you please provide us with a brief description of your current setup using this link as a guide.
Make sure to describe your network configuration/topology, including any networking hardware currently in use, so we can have a clear understanding of how your devices are communicating.
Thanks!
