Why Can't I Log In to MT5? Common Problems and Fixes

You've typed your account number, double-checked the password, and selected what you think is the right server—but MetaTrader 5 still won't let you in. Few things are more frustrating than staring at a login error when you need to check a position or catch a market move.

If this sounds familiar, you're not alone. MT5 login problems are among the most common issues traders face. The good news is that most of them are straightforward to fix. Here's what usually goes wrong—and how to get back in.

The Usual Suspects: Credentials and Server Selection

The vast majority of MT5 login failures come down to one of three things: the wrong account number, an incorrect password, or the wrong server .

Passwords are case-sensitive, so a stray capital letter or an accidental Caps Lock key can trigger an "Authorisation Failed" or "Invalid Account" error . Copying and pasting your password directly from your broker's welcome email eliminates the risk of typos .

Server selection trips up many traders. You might have the correct account number and password, but if you've chosen the wrong server—say, logging into a demo server with a live account, or selecting a different broker's server entirely—MT5 will reject the connection . Your broker's welcome email or client portal usually lists the exact server name you need .

When It's Not Your Fault: Connection Issues

Sometimes the problem isn't your credentials at all. Network connectivity is another frequent culprit. If the connection indicator in the bottom-right corner of MT5 shows red or keeps updating, the platform can't reach the trading server .

Firewalls or antivirus software can block MT5's internet access without warning . Adding MT5 to your security software's allowed list often resolves this . Running multiple instances of MT5 or other trading platforms simultaneously can also create conflicts .

In some cases, the issue may be tied to your network environment. Traders have reported that MT5 works fine on Wi-Fi but fails on LTE, with the problem sometimes traced to how the broker's server handles that type of connection .

A Quick Troubleshooting Checklist

Before you contact support, work through these steps:

• Verify your account number—check for any incorrect digits
• Retype your password or copy it from your welcome email
• Confirm you're selecting the correct server for your account type
• Check your internet connection and restart your router if needed
• Disable firewalls/antivirus temporarily to test, or add MT5 to the allowed list
• Restart MT5 completely, or try the WebTrader version to rule out a local installation issue

Beyond Login: What Happens After You're In

Once you're logged in, the next challenge begins—keeping an eye on your positions and quotes without leaving MT5 open and visible on your screen all day.

This is where Camovia Tray fits in. It turns your MT5 (or MT4) into a system tray tool, so you can check live quotes by simply hovering over the tray icon [citation:product_knowledge]. View your open positions—including symbol, direction, lot size, open price, and current P&L—without bringing the full MT5 window back up [citation:product_knowledge]. And when you need to close a trade, you can do it directly from the floating order panel [citation:product_knowledge].

For traders who prefer to keep their workspace clean, Camovia Tray also offers a one-click hide feature that removes MT5 from the taskbar and Alt+Tab menu [citation:product_knowledge]. The data stays entirely local, read directly from your terminal without anything uploaded [citation:product_knowledge]. It runs on Windows 10 and 11, supports both MT5 and MT4, and offers a free trial for new users [citation:product_knowledge].

Getting logged in is step one. Staying on top of the market once you're in—without having to keep MT5 front and center—is what makes the daily routine smoother.
