TRY THIS Oracle Cloud with iPBX 2021 "404 not found"

I have been using Putty to access the instance. Just today. but accident, I double clicked on the instance name and was immediately logged in. Go figure. No telling what is going on with that nonsense.

Well you have set putty up with the necessary putty private key (*.ppk) - and you 'Saved' that configuration.
When you double clicked it putty used your remembered config to log you in as user ubuntu , as you accessed via the *.ppk there would be no danger that anyone else has your private key.
Hopefully you have set a password for user root@your-OracleInstance-IP and I remember something about disable password login in the sshd_config file

The issue is, as I kept mentioning, was being blocked at port 22 without an apparent reason, then all of a sudden not blocked.

A little late to the party here but could the cause be rooted in the whitelist of IP? I struggled with that with Oracle hosted PBX until I set up OpenVPN and began connecting via 10.8 address.

In the short term, I did get my un-white-listed home IP able to connect by using the Oracle console connection to remove (del-acct) the old home IP and then add (add-ip) the new home IP assigned by my service provider.
