Hi, for a few days now a site I manage no longer sends emails from any form. I installed wp-mail-smtp to try to solve it by entering the hosting email account. Trying the email test I notice that it takes about a minute and then returns 500 internal server error.
Request Timeout
This request takes too long to process, it is timed out by the server. If it should not be timed out, please contact administrator of this web site to increase ‘Connection Timeout’.
I also tried other smtp servers like gmail and I get the same error.
If I use php default mailer instead I get this error:
Versions:
WordPress: 5.7.1
WordPress MS: No
PHP: 7.4.9
WP Mail SMTP: 2.7.0
Params:
Mailer: mail
Constants: No
Server:
PHP.mail(): No
Apache.mod_security: No
PHPMailer Debug:
Could not instantiate mail function.
Debug:
Mailer: Default (none)
PHPMailer was able to connect to SMTP server but failed while trying to send an email.I hope someone can help me.
Thanks
