You can increase Pemorla's own log verbosity to debug and see what's going on.
I have hydroxide ProtonMail bridge thingie running locally, it works as SMTP server, I think I just pointed my Permombler to it, host port, login, password — and it worked, I didn't spend a lot of time on it.
But it might be tricky for remote SMTP server.

Either that or find a way to supply up-to-date root certs to the Elixir module that is used to send emails — I'm not knowledgeable enough about it to help.
If you use Proton, this might work for you, this is what I use: https://github.com/emersion/hydroxide
It's easy to set up, but I'm not sure it's a good idea to run it on your VPS as it would have access to all your emails, at least make sure it accepts connections on localhost only.

Another solution might be using sendmail adapter with msmtp — I've never used this setup myself, but check it out, might be easier to pull off than both: working with remote SMTP as is and setting up your own SMTP server to run locally. msmtp uses systemwide certs in /etc/ssl — so this shouldn't be a problem, you need a very basic .msmtprc: host, port, from, user — you can specify password right in it, or put it in .netrc
