Salt Minion cannot reach Salt Master at port 4505. What workaround can I use?

Question

I've a Salt Master server and some Minions that work well. All the configuration is by default.

I've one Salt Minion in a really strict network. Running

 nc -v -z salt.master.ip.addr 4505

returns

4505 (tcp) failed: Connection timed out

And obviously it cannot connect to the Master. I'm not an expert on network topics and I haven't found a nice workaround. What can you suggest?

Thanks!

You can change the port the master listens on with the publish_port option in the master config.

https://docs.saltstack.com/en/latest/ref/configuration/master.html#publish-port

You would also have to change the port the minion uses to connect to the master: https://docs.saltstack.com/en/latest/ref/configuration/minion.html#master-port-syntax

Have you checked the firewall on your Salt Master?
