Mailpit doesn't work (404 error)

[Jessy]

Hello I’m on macOS (silicon), lastest version

Lastest version of Local (very slow btw).
Mailpit doesn’t work (error 404) http://localhost:10099.

How to make it work again ?

Hey @Jessy!

You’ll probably want to double check that you are actually on the Apple Silicon version of Local and not using the Intel version.

Local Slow on Mac

So, anyone who has encountered this problem on a Mac with M (apple silicon). The solution is to manually update the program to the Apple Silicon version (Releases - Local). The problem was that when the program automatically updated, the Intel version was loaded. [Screenshot 2025-05-06 at 09.20.49] [Screenshot 2025-05-06 at 09.19.55]

For Mailpit you can try this after checking you have the right version:

MailPit not starting On OSX

Thanks for sharing your sites.json, @sebastian. It looks correct to me. One thing you can try is to force Local to recopy the mailpit binary on startup (steps below assume macOS, Windows users reading this should follow these instructions instead). Stop any running sites. Quit Local. Open the Finder and choose Go → Go To Folder… Enter ~/Library/Application Support/Local/lightning-services and press Enter. Delete the folder named ‘mailpit-1.12.1+0’, but leave the Finder window open. Make sure …

I update Local from local. (It was already installed).

I already suppression Lightning services folder. Doesn’t fix anything.
Mailpit is installed, I guess it’s port problem

(very slow btw) … I update Local from local. (It was already installed).

Updating the Intel version would still leave you on the Intel version, which could be slow/broken if you’re on Apple Silicon.

Please could you find the Local app in your Applications folder (command-click Local in your Dock), then right click the app icon and choose Get Info.

Do you see “Application (Apple silicon)” or “Application (Intel)”?

If you see “Application (Intel)” you should download the latest Apple Silicon release instead:

[Jessy]

Indeed the update doesn’t take the good version of the app.

But mailpit doesn’t work even if I delete it and launched again local app.

[nickc]

Thanks for changing to the Apple Silicon version, @Jessy, that should help with your speed issue!

For the Mailpit issue, please could you follow the steps here carefully once more, but delete all “mailpit” folders including the newer one named mailpit-1.24.1+0. We’ve seen that solve the issue in previous cases.

It’s likely that you have the Intel version of Mailpit instead of the Apple Silicon one, and those steps should take care of this for you.

If the above doesn’t help, feel free to share your Local logs.

[Jessy]

I already delete it as I’ve said before. It came back but I still have the problem

[nickc]

Thanks for your logs and sorry you’re still seeing this issue, @Jessy.

I don’t see anything in logs that should prevent Mailpit from working.

You could try re-importing this site into Local from the stored files on disk:

[Jessy]

I delete MAilpit folder
The problème appears on every sites.

Now all my sites doesn’t work anymore.

I have this error message

Is it a Way to fix it ?

Best regards

@Jessy

php-8.3.8+0

That is one of the older patch versions of PHP 8.3. Is there any change in things if you update the version of PHP, for example, 8.3.23?

[Jessy]

It’s already 8.3.23 PHP version.

I have this error message When I start a site
"Uh-oh! Unable to start site.

Error: EXIST: file already exists, mkdir ‘/Users/ jessyb/Library/Application Support/Local/run/ router/nginx/conf/includes’"

I’m on apache not nginx

[Nick-B]

Hey @Jessy! As a test, if you create a new blank site in Local can you access that? Or do you get the same error?

[Jessy]

With a blank new site I have this error “http://localhost:10026”

[Nick-B]

What’s the error message in the browser window @Jessy? Feel free to share as screenshot.

Did you just use Local’s preferred settings?

Do you have the same problem if you change your Router Mode to Site Domains? Preferences>Advanced>Router Mode

[Jessy]

Yes it’s the message from the browser.

I’m already on Site d’omanis for router mode.

I’ve just try cloning website and I have these Errors.

[nickc]

Thanks for sharing this error, @Jessy.

It looks like you may be missing files from your Local router folder, or there could be permissions issues preventing Local from running.

You could try this:

1. Quit Local.

2. Open a terminal and run this command, exactly as written:

   rm -rf ~/Library/Application\ Support/Local/run/router
   

3. Open Local and try to start your site.

If you see new errors please share them, we’re happy to take a look.

[Jessy]

@nickc

rm -rf ~/Library/Application\ Support/Local/run/router

Same error after cloning process.
BTW my “template site” still have mailpit trouble

[Nick-B]

Hey @Jessy!

Just to cross off a couple of things here can you verify that:

• You are using this device as an Admin user?

• That the device has plenty of disk space?

Moving on from those, in order to refresh here and start with a clean slate could you give the below troubleshooting steps a try?

• Export any sites that you have on Local and save them to a folder somewhere on your computer: Backup a Local Site - Local

• Fully uninstall Local from your computer following your OS specific steps here: Uninstall Local - Local

• Install the latest version of Local on this link: Releases - Local

• Once installed, please restart the computer.

• When the computer is restarted and turned on, close any applications that automatically run in the background (AntiVirus, Firewall, and other Developer applications included).

• Check and see if the issue still persists. If so, please provide us with an updated log: Retrieve Local’s Log File - Local

Keep us posted and we’d be happy to help further!
