Message "table id=table-members - No response from back-end" when filter devices in a dynamic group

Recently I got this error message when I wanted to add the devices to a dynamic group according to filters:

"table id=table-members - No response from back-end"

Does anyone have any ideas? Thank you in advance!

is it a repeatable error? For me it looks like a communication error between browser and server - some timeout, so a temporary error.

no, the error cannot be reproduced. the message has not appeared since then
