SMTP Error: Could not connect to SMTP host. Failed to connect to server
Posted: 26 May 2026, 17:46
Hi,
I changed the mailer in my Joomla 6 project from php to smtp. Testmails are working, but nor the checkout-process. If I am finishing the checkout-process I am getting a message: "SMTP Error: Could not connect to SMTP host. Failed to connect to server". But Joomla itself is connected to the server.
Does somebody has an idea?
Best regards Uwe
