Hi all, Banging my head against an inexplicable (to me) problem which has arisen when moving off sandbox mailgun SMTP to a new domain. A few hours ago I switched the URL setting in app.yml to the new domain, and install is working fine. Then I moved to email settings and changed necessary settings in app.yml to the Mailgun settings for my verified domain (all DNS is good to do in Mailgun). Instead of seeing the SMTP settings I saved in app.yml, I’m only seeing one line under “Delivery Method” that shows “Arguments -i”. Here’s a screenshot: [תמונה] Been searching this forum and haven’t seen any reference to this issue. If anyone has any ideas, I’m all ears.

Some questions: Did you complete a ./launcher rebuild app after both app.yml changes? Are you seeing any other issues? Errors in /logs, browser console, etc? Have you verified that your app.yml is valid? http://www.yamllint.com/ Please upload (or copy paste in) your app.yml making sure to remove passwords first! Also, for a support topic, please share a link to the forum.

Thanks, Joshua. Here’s a link to the forum: http://caldata.net In answer to your questions: Yes, ./launcher rebuild after all app.yml changes No errors in logs but browser console is reporting “Failed to load resource: the server responded with a status of 502 (Bad Gateway)”. However, this seems to be an intermittent error.

I’m not seeing anything jump out at me from the app.yml. _Off Topic: when pasting in code, it is helpful to surround it with 3 back ticks. Reference: http://commonmark.org/help/tutorial/07-code.html_ The only thing I haven’t seen before is SEGMENT_IO_KEY. I’m assuming that’s related to this plugin? GitHub - kylewelsby/discourse-segment-io-plugin: Emits user events to segment.io · GitHub Does the error still occur when the plugin is removed from your app.yml?

Thanks, Joshua. For the code pasting tip, and the response. Yep, that’s a plugin for Segment.io, and the mail settings were working when I was using Mailgun’s sandbox SMTP settings and had that same plugin installed. I can try commenting that out of app.yml and see what happens, but m y guess is that’s not the problem. Will let you know if anything changes when I have a chance to try that later.

@jomaxro FYI, I’m commented out the Segment.io plugin (and all custom plugins) and am still seeing the same error on the email settings page in admin.

I’ve also now tried going back to Mailgun sandbox SMTP settings and creating a Sparkpost account and using those SMTP settings. Still only seeing the “arguments -i” line in the email settings admin page. I’m totally confused. Anyone have any ideas on what else I can try?

The issue is because of this line ## Plugins go here env: SEGMENT_IO_KEY: XXXXXXX You are redefining the “env” key (which is defined earlier) and thus all of the “DISCOURSE_” settings are gone… To fix it, you need to move the “SEGMENT_IO_KEY” under the “#DISCOURSE_CDN_URL” line, like so env: LANG: en_US.UTF-8 # DISCOURSE_DEFAULT_LOCALE: en # [...] ## The CDN address for this Discourse instance (configured to pull) #DISCOURSE_CDN_URL: [REMOVED] SEGMENT_IO_KEY: XXXXXXX ## The Docker container is stateless; all data is stored in /shared volumes: - volume: host: /var/discourse/shared/standalone guest: /shared - volume: host: /var/discourse/shared/standalone/log/var-log guest: /var/log

@zogstrip Thank you! That did it. I saw the extra “env” statement there, but didn’t stop to think it would redeclare all environment variables. Thanks again, it’s a relief to see my SMTP settings back :slight_smile:

We’ve now surpassed my email knowledge, sorry! Perhaps @zogstrip might have a thought or two, he does a lot of email related development.
