Hi all, I’m having an extremely unpleasant time with Bamboo/Mailgun in production. I’ve tested the MailgunAdapter for Bamboo from my local machine and everything works well, however in production I’m getting this error: ** (Bamboo.ApiError) There was a problem sending the email through the Mailgu…

Hey all, @phcurado @wanton7 @derek-zhou @sfusato first, thank you all for trying to help. I’m a lone developer trying to get my side project running and it’s extremely useful to have someone to talk to about the problems that I run into along the way. I reached out to Mailgun’s support team and I’…

How did you check the key on the server? I would guess that this a runtime env problem. System.get_env() will be evaluated at compile time if you put on prod.exs. If you don’t have those variables during compilation they will be nil. If you want your environment variables during runtime you should…

Good question. I checked it by logging into the server and running System.get_env(). To be honest I doubt that they would be nil during compilation because this would have cause a lot more problems, for example I’m also reading my DB URL via System.get_env() in the same file and my DB connectivity w…

I think you can try getting the envs with Application.get_env(:sleep_rescue, SleepRescue.Mail.Mailer). If everything looks correct you can test the same config in dev.exs locally and retry the email request.

Yep, running in in local dev.exs works as expected

Are you perhaps using EU zone? Quote from here https://stackoverflow.com/questions/63489555/mailgun-401-forbidden I had this problem when my domain was in an EU zone. When you’re using an EU zone, you have to specify it in the config - this isn’t clearly explained by Mailgun. So it would be somet…

Yep, I’m using the EU zone in configs and that’s how I’ve set it up on the Mailgun side. Note that I’ve successfully tested it locally

Good question and for a second I thought that it could be the solution. I’ve checked my Heroku region and it’s set to EU and I’ve also tested the URL https://api.mailgun.net/v3 just in case, but that didn’t help.

I haven’t used Mailgun but I did a really fast peek at their docs here https://documentation.mailgun.com/en/latest/api-intro.html#base-url that you need to decide when creating a domain is it for US or EU. Are you sure you created your domain for EU? Base URL All API calls referenced in our docum…

Yes, like I said in my previous post: Good question and for a second I thought that it could be the solution. I’ve checked my Heroku region and it’s set to EU and I’ve also tested the URL https://api.mailgun.net/v3 just in case, but that didn’t help.
