 By default, uploads to Nextcloud are limited to a max of 3600s. You can adjust the upload time limit by providing `--env NEXTCLOUD_MAX_TIME=3600` to the docker run command of the mastercontainer (but before the last line `nextcloud/all-in-one:latest`! If it was started already, you will need to stop the mastercontainer, remove it (no data will be lost) and recreate it using the docker run command that you initially used) and customize the value to your fitting. It must be a number e.g. `3600`.
 
 ### How to adjust the PHP memory limit for Nextcloud?
-By default is each PHP process in the Nextcloud container limited to a max of 512 MB. You can adjust the memory limit by providing `--env NEXTCLOUD_MEMORY_LIMIT=512M` to the docker run command of the mastercontainer (but before the last line `nextcloud/all-in-one:latest`! If it was started already, you will need to stop the mastercontainer, remove it (no data will be lost) and recreate it using the docker run command that you initially used) and customize the value to your fitting. It must start with a number and end with `M` e.g. `1024M`.

 ### What can I do to fix the internal or reserved ip-address error?
 If you get an error during the domain validation which states that your ip-address is an internal or reserved ip-address, you can fix this by first making sure that your domain indeed has the correct public ip-address that points to the server and then adding `--add-host yourdomain.com:<public-ip-address>` to the docker run command of the mastercontainer (but before the last line `nextcloud/all-in-one:latest`! If it was started already, you will need to stop the mastercontainer, remove it (no data will be lost) and recreate it using the docker run command that you initially used) which will allow the domain validation to work correctly. And so that you know: even if the `A` record of your domain should change over time, this is no problem since the mastercontainer will not make any attempt to access the chosen domain after the initial domain validation.
