Experiencing parse error with Mailgun and Laravel despite setting up domain and secret in .env file

Help! I’m stuck with a weird error in my Laravel app.

I’ve set up my Mailgun domain as mg.mydomain.com.ng and added the secret to my .env file. But when I try to register a new user, I get this strange exception from GuzzleHttp:

InvalidArgumentException
Unable to parse URI: https:///v3/mg.mydomain.com.ng/messages.mime

I’m pretty sure I’ve followed all the steps correctly, but something’s not clicking. Has anyone run into this before? Maybe I’m missing a small detail somewhere in the configuration? Any tips or tricks to debug this would be super helpful!

I’ve dealt with this exact problem before, and it can be super frustrating. One thing that’s easy to overlook is the MAILGUN_SECRET key in your .env file. Make sure it’s the private API key, not the public one. Mailgun provides both, and using the wrong one can cause weird errors like this.

Another thing to check is your Mailgun sending domain verification. Even if you’ve set it up correctly in your .env, if it’s not fully verified on Mailgun’s end, you might run into issues.

Have you tried logging the full Mailgun configuration at runtime? Sometimes what you think is in your config isn’t actually what Laravel is using. Adding a debug log right before the mail send can reveal surprising issues.

Lastly, if none of that works, try setting up a test route that dumps your entire mail configuration. It might reveal something unexpected in how Laravel is interpreting your settings.

hey ethan, had dis issue b4. check ur .env file, make sure MAILGUN_DOMAIN is set right. no extra spaces or quotes. also, try MAILGUN_ENDPOINT=https://api.mailgun.net/v3

if that dont work, clear config cache with php artisan config:clear. hope this helps!

I’ve encountered a similar issue before, and it’s often related to how Laravel is parsing the Mailgun domain. Check your config/services.php file to ensure the Mailgun domain is correctly set there as well. Sometimes, Laravel doesn’t pick up the .env changes immediately.

Also, verify that your MAILGUN_DOMAIN in the .env file doesn’t have any extra spaces or quotation marks. It should be just the plain domain string.

If those don’t solve it, try running php artisan config:cache to refresh your configuration cache. This has resolved similar parsing issues for me in the past.

Lastly, double-check your Mailgun API endpoint. Make sure you’re using the correct region (EU or US) in your configuration. An incorrect endpoint can cause similar parsing errors.
