an error occurred while registering

[minor jungle]

Does anyone know why it's like this? My previous VPS had a problem, couldn't be accessed, so I made a new VPS, then reinstalled and backed up the database, other features are safe, just register, can't

By default, we only allow users to make one account per IP address. to disable this,
head to /admin/settings and set REGISTER_IP_CHECK to false.

If you have proxied your domain through Cloudflare, than you need to configure your nginx to grab the real ip address. Read into:

this is different error

You can create a dummy user in your controlpanel db with a higher ID using SQL. That way the DB will increment the id from that number (you can delete the user after creation, no worries)
For that just insert a entry in the users table at the controlpanel db, you can set everything nulle xcept the email and the id. Set the ID to a high number like 100 (higher than the usercount at ptero to be sure)
You may delete the entry afterwards. Every new user will be given a id (and thus external_id on ptero) that will be incremented on the id you've set. E.g. the next user will have the id 101, next 102...

i had this issue and this fixed it

Yes, it seems like something you really can't control.
