I have suddenly lost the ability to ssh into my raspberry pi.

the connection attempt hangs for sometime and eventually returns a "Operation timed out error".

SSH access is enabled on the Pi. The Port is set to 55555

I can successfully ping the Pi's IP address.

The verbose output of the ssh attempt is:

(base) kevin@KBurnham-MBP16 ~ % ssh -i ~/.ssh/id_rsa_pi [email protected] -p 55555 -vvv
OpenSSH_8.1p1, LibreSSL 2.7.3
debug1: Reading configuration data /Users/kevin/.ssh/config
debug1: Reading configuration data /etc/ssh/ssh_config
debug1: /etc/ssh/ssh_config line 47: Applying options for *
debug2: resolve_canonicalize: hostname 192.168.1.48 is address
debug2: ssh_connect_direct
debug1: Connecting to 192.168.1.48 [192.168.1.48] port 55555.
debug1: connect to address 192.168.1.48 port 55555: Operation timed out
ssh: connect to host 192.168.1.48 port 55555: Operation timed out

As I said, it was working fine, however, I ran and ansible playbook that may have changed some settings, I am unsure how to further troubleshoot the issue.

  • are you sure 192.168.1.48 is the pi? Just because something is there doesn't mean it's the pi (unless you have static IP set up or reserved the address in DHCP of course)

  • according to hostname -I that is the ip address. Is that sufficient to be sure?

the aforementioned ansible playbook that I started but terminated had activated the firewall and restricted acceptable ports for ssh. Once I disabled it I was able to ssh as before.
