http and smtp both fail

Any update about this? I have same issue.
SMTP and API are working in Outlook and manual PHP test, but plugin always returns test failure :/

Same issue…. me too! I wish we’d get some help from the developers!

Me too.
In fact, I didn’t see this post so I started this one a bit earlier today.

OK, based on reading through more posts here, I got it working at least well enough to get a “Mailgun HTTP API Test Success” response.

For some reason, it seems like maybe having Tags might be part of the problem. ???

I followed the suggestions in the HTTP API Configuration post (of course, substituting my credentials), and the test came through successful.

Hope this helps someone, since the authors seem to be MIA.

Just a followup, I made a few other posts about this. Had the same issue with a client we upgraded his dedicated server week or so ago. We updated from PHP 5.4.x to 5.6.x and that is when the Mailgun plugin stopped working.

Note since our client was using SMTP that is what we stayed with for this specific issue.

After no success with anything we tried, we uploaded the ‘Postman SMTP’ plugin and used his Mailgun SMTP login credentials and worked perfectly.

So if you plan on using SMTP, can’t get it to work the Postman SMTP might be a possible solution. It was for us.

I have the same issue.

Running Ubuntu 16.04 and PHP 7.0. I’m thinking since the above user has had problems since a PHP upgrade, we don’t have the required modules or something. I’ll do some research into this and hopefully have a solution later today.

Scrap that, i checked the logs on mailgun as i was trying to use the sandbox. My domain is not yet verified and as a result, it failed.

Hope that might help some of you.

Check your developer console when you’re on the settings page for Mailgun. Do you see any 500 errors relating to admin-ajax.php? That was what I was seeing, and the problem was PHP was running out of memory, so I increased my max memory in wp-config.php and everything began working again.

See this for one explanation of SMTP failing.

For OP: the Mailgun Domain Name field is the configured Mailgun domain name, not the SMTP hostname.
