SMTP Error: Could not connect to SMTP host. Failed to connect to server

I made all the correct settings and it doesn’t work, it gives me these errors:

SMTP Error: Could not connect to SMTP host. Failed to connect to server

WP SMTP connection error

Seems like there are some problems with the enterd information. Please re-check & re-enter it and hit the “Save changes” button.

We recently made some changes regarding how we save the username and password in the database, namely we are encrypting them, so that might be the reason for the connection error. Re-entering and saving them should solve the issue.
