STOP RIGHT THERE!

You may not have a mail application configuration problem after all (ssmtp/
msmtp), but you definitely have a network/server connectivity problem.  You 
need to sort out the network connection first, before you look at your smtp 
client configuration.

So you can access the server, but not connect to the port.

Can you connect to ports 25, or 465?

Can you connect to 'smtp-relay.gmail.com' instead?

If you cannot see an open port, then either your network is misconfigured, or 
you've annoyed Google enough to block your access to their smtp service.

Ah!  I have found Google logs your IP address and when this changes they may 
choose to block your connection to their service.  Often it sends you a 
message in your backup email address/phone asking you to confirm if the device 
and new IP address you are trying to connect from is you and yours.

Throwing a VPN in the works may trigger the above security (re)action, when 
your client is using an 'App Password' token, as opposed to the full OAUTH2 
exchange.

Google's modus operandi is arguably predicated on recording your data, your 
location, your movements, your purchases, your contacts, your written/spoken 
word, your interests, your thoughts, etc.  Selling advertisements is a 
monetisation mechanism to facilitate the high cost of their operation.  They 
are not unique in this endeavor, other Big-Tech quasi-monopolies are 
performing the same role.  The offer of 'free' internet services is the 
honeypot used to attract footfall.
