Hi guys,
I have an error on one of my client’s sites. It used to work, but then stopped. Could not connect to SMTP host. Any ideas, please?

EMAIL DELIVERY ERROR: the plugin WP Mail SMTP v2.5.1 logged this error during the last time it tried to send an email:
Mailer: Other SMTP
SMTP Error: Could not connect to SMTP host.
Consider running an email test after fixing it.
Thank you in advance.
