When signing up as new client I get:

System message
Email address is invalid (9999)

Email is actually valid, here's payload:

Code:

{
  "CSRFToken": "8772ef43e0054029b74e739104bc6655",
  "first_name": "Velopulsas Test 2",
  "email": "[email protected]",
  "password": "Dadadada123-",
  "password_confirm": "Dadadada123-"
}

Response:

Code:

{"result":null,"error":{"message":"Email address is invalid","code":9999}}

I tried different combinations with no luck. I have https enabled and configured which was not after installation.

Does your server have a working DNS configuration?
DNS validation is performed when checking if an email address is valid.

Yes, it helped! I've added my local DNS server running on 192.168.31.50, where PiHole is located to namservers declaration in /etc/netplan/default.yaml:

Code:

network:
  version: 2
  renderer: NetworkManager
  ethernets:
    end0:
      dhcp4: false
      addresses: [192.168.31.61/24]
      routes:
      - to: default
        via: 192.168.31.1
      nameservers:
        addresses: [192.168.31.50]

Explanation:
192.168.31.61 is a machine where FOSS is running
192.168.31.1 is a router which gives out addresses (DHCP)
