MariaDB/MySQL runs on port 3306 by default on all Ultra Web Hosting servers. But since this is one of our most-visited articles, we've expanded it into a quick reference for every common port you might need when connecting to your hosting account.
MariaDB/MySQL Port: 3306
All Ultra Web Hosting servers use the standard MariaDB/MySQL port. For applications running on the same server (WordPress, Joomla, etc.), use localhost as the database host, not an IP address or port number.
- ✓ MySQL/MariaDB: port 3306
- ✓ Database host for local apps: localhost
- ✓ phpMyAdmin: accessible through cPanel (no port needed)
- ✓ Remote MySQL: must be enabled in cPanel first
01. Database Ports
| Service | Port | Notes |
|---|---|---|
| MariaDB / MySQL | 3306 |
Standard port. Use localhost for apps on the same server |
| PostgreSQL | 5432 |
Available on VPS/dedicated plans |
02. Email Ports
| Service | Port | Encryption | Notes |
|---|---|---|---|
| IMAP | 993 |
SSL/TLS | Recommended for incoming mail |
| IMAP | 143 |
STARTTLS | Alternative if 993 is blocked |
| POP3 | 995 |
SSL/TLS | Downloads mail to device |
| POP3 | 110 |
STARTTLS | Alternative if 995 is blocked |
| SMTP (outgoing) | 465 |
SSL/TLS | Recommended for sending mail |
| SMTP (outgoing) | 587 |
STARTTLS | Alternative if 465 is blocked |
| SMTP | 25 |
None | Blocked by most ISPs. Do not use for client connections |
For complete email setup instructions, see our guides for iPhone/iPad, Android, Outlook, or our Email Troubleshooting Guide.
03. Web and Control Panel Ports
| Service | Port | Notes |
|---|---|---|
| HTTP | 80 |
Unencrypted web traffic (redirects to HTTPS) |
| HTTPS | 443 |
Encrypted web traffic (standard) |
| cPanel | 2083 |
HTTPS access to cPanel |
| Webmail | 2096 |
HTTPS access to Roundcube webmail |
| WHM | 2087 |
Server admin (resellers only) |
04. FTP and File Transfer Ports
| Service | Port | Notes |
|---|---|---|
| SFTP / SSH | 22 |
Recommended. Encrypted file transfer |
| FTP | 21 |
Use with Explicit TLS for encryption |
| FTP Passive Range | 49152-65534 |
Used for FTP data connections in passive mode |
We recommend SFTP (port 22) over FTP for all file transfers. It's encrypted and works through firewalls more reliably. See our FTP Client Setup Guide for instructions.
05. Connecting to MySQL Remotely
By default, MySQL connections are only allowed from localhost (the same server). If you need to connect from an external application, a local development machine, or a different server, you need to whitelist your IP address first.
- Log into cPanel - go to your hosting control panel
- Click "Remote MySQL" - in the Databases section
- Add your IP address - enter the IP you'll be connecting from. You can use
%as a wildcard, but we don't recommend it for security reasons - Connect with your database tool - use your server's hostname or IP, port 3306, and your database username/password from cPanel
Never add % (all IPs) to Remote MySQL unless you absolutely need it and your database user has a very strong password. It opens your database to connection attempts from anywhere on the internet. Always whitelist specific IPs instead.
Connection String Examples
# MySQL command line
mysql -h yourserver.ultrawebhosting.com -P 3306 -u dbuser -p dbname
# PHP (PDO)
$pdo = new PDO('mysql:host=yourserver.ultrawebhosting.com;port=3306;dbname=yourdb', 'user', 'pass');
# WordPress wp-config.php (local - most common)
define('DB_HOST', 'localhost');
# WordPress wp-config.php (remote)
define('DB_HOST', 'yourserver.ultrawebhosting.com:3306');06. Common Port-Related Issues
"Can't Connect to MySQL Server on 'localhost'"
If your application can't connect to the database, the issue is almost never the port. The most common causes are: wrong database name (cPanel prefixes it with your username), wrong database user credentials, or the user hasn't been granted access to the database. Check all three in cPanel > MySQL Databases.
"Connection Timed Out" on Email Ports
If your email client times out when connecting, your ISP or network may be blocking the port. Try the alternative port (e.g., 587 instead of 465, or 143 instead of 993). Corporate and hotel Wi-Fi networks frequently block email ports. Test on a different network to confirm.
cPanel Won't Load on Port 2083
If you can't access cPanel at https://yourserver:2083, your IP may be blocked by the server firewall. Visit my.ultrawebhosting.com to unblock your IP, or try accessing through your client area which has a direct cPanel login link.

Open a Support TicketQuick Recap: Common Ports
The ports you'll use most often:
- MySQL/MariaDB: 3306 - use
localhostfor same-server connections - Email: 993 (IMAP), 465 (SMTP) - both with SSL/TLS
- SFTP: 22 - for encrypted file transfers
- cPanel: 2083 - HTTPS access to your control panel
- Web: 443 (HTTPS) - standard encrypted web traffic
