SMTP email service is not working

[evojewel]

Configured Email Server Settings (SMTP) from from admin panel through Customization/Config with mailgun as service provider. After inviting a member it showed "The invite has been sent to the user's email." but the email did not received and in backend there is a timeout error happening

Steps to reproduce the behaviour :

1. Go to '/admin/customization/config'
2. Configured Email Server Settings (SMTP) with mailgun as service provider (Authentication:Plain, Port:465)
3. Got to '/admin/member_manager/invitations/new' submit email address and it will show the email was sent
4. Go to the instance console of your cloud provider where the forem is hosted and hit 'journalctl -f -u forem-rails.service' there will be a timeout error
5. Error log : Error log.txt

Expected behaviour : The email should receive

OS : Linux

Cloud Provider : AWS

Additional context : Tried with Sendgrid and same timeout error is occurring, Changing port is not making any changes

Hello there, I'm not sure how much this matters but could you please try lowercase plain and restart the server? What did you use for the mailgun address?

[evojewel]

@maestromac It is already plain and the address is smtp.eu.mailgun.org

[maestromac]

What's your from and reply email address? I see the following email in your log [email protected] which looks like an autogenerated email address.

I also have the some problem, after testing out 'journalctl -f -u forem-rails.service' it also print out this error:

ERROR -- : [ActiveJob] [ActionMailer::MailDeliveryJob] [4126839f-55da-4ac1-874d-cbff56dfe42f] Error performing ActionMailer::MailDeliveryJob (Job ID: 4126839f-55da-4ac1-874d-cbff56dfe42f) from Async(default) in 5033.56ms: Net::ReadTimeout (Net::ReadTimeout with #<Socket:(closed)>):

@Dani4kor @igrir may I please know which email services are you both using?

@Dani4kor @igrir may I please know which email services are you both using?

I am using mailgun, I tried all the ports and the result is the same. I also tried to use Amazon's SES and looks like it also return the same error

this is the result from my journalctl logs
