If you want to increase your droplet limit you’ll need to follow these steps:
You can request a Droplet limit increase via your DigitalOcean Control panel. Then go to ‘Settings’ -> ‘Profile’ -> And hit the 'Increase’ button.
Once there, you’ll want to click the Increase link to open the form to increase your account’s current limit.if you’re having a limit of 25 the option to increase the limit to 50 should work instantly and the limit will be increased to 50 droplets.
If you require a higher limit, then fill out the form and after you’ve submitted the form, it will then be passed on to DigitalOcean’s support team for review.
Hope that this helps!
