Each month you get a fixed amount of requests and data. If you reach this limit, your space gets closed temporarily for public access.
When your next subscription period starts, your space will automatically be opened again - and we reset the counter for requests and data. If you want more requests, data, or storage - you can upgrade to a paid subscription that includes larger quotas.
Your spaces might also get closed due to exceeding storage quota limits if you downgraded your plan and your new quotas are smaller.
The storage quota limits include the number of spaces, number of files and folders per space, maximum file size, and total data stored.
If this is the case you will need to delete files, folders or spaces to open your spaces again.
