Problem with port binding

[julian-ladjani]

Description

Hello,
I use colima since yesterday, I have a dns container working perfectly with docker, since I use colima, Ihave this problem:
docker: Error response from daemon: driver failed programming external connectivity on endpoint nice_bell (b688f5012ab945b7d85e4f85a1ead26960501561deb75c417db4333e27b85db7): failed to bind port 0.0.0.0:53/tcp: Error starting userland proxy: listen tcp4 0.0.0.0:53: bind: address already in use.
(same with udp),
When I use 54 port (for exemple), it work fine.
Maybe it's a permissions problem or something like that?

Additional context

No response

It simply means something is already using port 53.

You can check the program using it by running the following command.

lsof -nP -iTCP:53 | grep LISTEN

I tested with netcat before in addition to lsof (by listening to port 53 directly).
Since we did not find a solution, we installed a dnsmasq and it works perfectly but not with docker-compose with colima (works with docker desktop).

I tried with two macs, it gives the same result
