Whonix-Gateway stops responding to DNS requests after some time

I’m using Whonix Gateway with multiple custom workstations to proxy traffic via Tor - around 5 clients at once, each with different IP address and such. After some time, let’s say 24 hours, I can no longer resolve DNS on the workstations until I restart Tor on Whonix-Gateway. Normal traffic still works fine. What could be the issue?

Are you sure it’s only DNS requests and not also TCP? How did you test that?

Existing long-running connections still work and I can still make new connections, as long as I don’t use hostnames, only IP addresses.

This happens both on Linux and Windows workstations. I’m also not doing anything crazy like sending 1000 DNS requests per second that would trigger something.
