Hi everyone, I get the following error when trying to upgrade to .22. I was unable to get it to work and ended up restoring a snapshot. Anyone have any ideas, or a direction to point me in?

You will be alerted that the website has an invalid certificate. Check that
the certificate fingerprint matches:

Then you can confirm the security exception and continue.

Have you looked at this link? OpenSSL error when running 'sudo mailinabox'

I had not seen that previously.

I’ll give that a shot next time I try to upgrade in a few days.

Thanks for your help!
