Trouble Integrating Mailgun with Laravel on DigitalOcean

I’m deploying the Laravel framework on a DigitalOcean server and attempting to use Mailgun for email services. Although my configuration seems correct, I’m encountering unexpected errors when executing my script. Below is an example of the error message I received:

Fatal error: Uncaught Error: Class 'HttpClientAdapter' not found in /app/vendor/laravel/Illuminate/Mail/Driver/MailserviceDriver.php on line 85
Stack trace:
#0 {main}

I’ve ensured all dependencies are installed and have followed the setup documentation carefully. Despite this, the application fails to find the necessary HTTP client class, which leads to the error above. Has anyone experienced a similar issue or found a workaround to resolve this problem?

hey, i had similar probs. try running composer dumpautload and double-check mailgun package version. sometimes cache or misconfigured autoload files cause these issues. not a sure fix but worth a shot.

During my troubleshooting on a DigitalOcean server, I encountered similar issues when integrating Mailgun with Laravel. It turned out that the problem sometimes stems from conflicting versions when multiple packages, including HTTP client libraries, are installed. In my case, ensuring the configuration aligned with the latest version of the Mailgun package was key. I encountered errors due to an outdated dependency that did not support the current structure expected by Laravel, so updating all related packages helped resolve the issue. Ensuring consistency in versioning across dependencies can prevent such errors.

hey, i had a similar headache. ended up manually adding the missing httpadapter alias in my config file and then run composer update. that finally made my mailgun work. sometimes u miss a tiny config detail that causes everything to break.

I faced a similar issue when trying to integrate Mailgun with Laravel on another project. After some investigation, I found that the problem was directly related to version incompatibilities between the Mailgun PHP library and Laravel’s mail driver. Clearing the composer cache and ensuring that both the Mailgun package and any related HTTP client libraries are upgraded to compatible versions fixed the error. It seemed that relying on outdated dependencies sometimes causes classes to not be found, so ensuring dependencies are in sync really helped in my situation.

I encountered a similar issue when working on a project with Laravel and Mailgun on a DigitalOcean droplet. After initially facing the same missing class error, I discovered that checking the dependency configuration in my composer.json and updating my packages resolved most conflicts. I had overlooked a subtle change in how certain HTTP clients were referenced in newer versions. Running a full composer update after verifying the package requirements fixed the issue. Additionally, ensuring that the environment variables were correctly set on the server played a crucial role in resolving the problem.
