You clicked the "Connect Wallet" button, the page flickered for a moment, and then nothing happened. No popup, no prompt, and no wallet address appeared. Don't doubt yourself—your browser really did block the request.

Most modern browsers treat popups that are not triggered directly by a user click as spam and block them by default. Your click did trigger the process, but if there is any asynchronous request in between or a delay longer than one second, the browser decides that the popup was not a direct result of the click and blocks it anyway.
Three Steps to Find Out Who Blocked It and Where
Step 1: Check the right side of the address bar for a blocked popup icon
In browsers like Chrome, Edge, and Brave, after a popup is blocked, a small icon appears at the far right of the address bar—usually a box with an X or a small red mark.
- [What to do]: Find this blocked popup icon
- [How to do it]: Look at the far right end of the browser address bar, next to the bookmark star icon
- [Done when]: You see that small icon, which confirms the popup was blocked. Click it, select "Always allow pop-ups from this site," then refresh the page and click "Connect Wallet" again
Safari users should be aware that Safari is one of the strictest browsers for popup blocking, and it does not give you any obvious warning after blocking. If you click connect in Safari and nothing happens, go directly to the top menu bar and select Safari → Preferences → Websites → Pop-up Windows, then set the current DApp website to "Allow."
Step 2: Check whether multiple wallet extensions are fighting each other
If you have MetaMask, OKX Wallet, and Phantom installed in Chrome at the same time, multiple extensions will try to respond when a DApp sends a connection request. In the end, none of them gets full control, and the popup is treated as a junk request by the browser.
- [What to do]: Keep only one wallet extension enabled and temporarily disable the others
- [How to do it]: Type chrome://extensions/ into the address bar and turn off all wallet extensions except the one you want to use
- [Done when]: You only see the icon of the wallet you kept in the upper right corner. Refresh the DApp page and reconnect
Step 3: Check whether antivirus software or a firewall is blocking it in the background
Windows Defender sometimes misidentifies MetaMask-related processes as potential threats and silently blocks them.
- [What to do]: Check whether Windows Defender has any event records related to MetaMask
- [How to do it]: Open Windows Security Center → Virus & threat protection → Protection history, and search the list for any blocked records containing "MetaMask." If you find one, click "Allow" or "Restore"
- [Done when]: There are no MetaMask-related blocking events in the protection history. Then reinstall the wallet extension
High risk warning: Never use a global setting that allows popups from all sites. If a phishing website successfully opens a popup that looks like a wallet confirmation screen and asks you to sign, you will not be able to tell the difference. Only allow popups for specific DApp domains that you trust.

If None of the Above Works
Look at the technical details on the DApp developer's side. Some DApps have problematic code—they make a network request or perform another asynchronous operation between the connect button click and the wallet popup, which breaks the browser's requirement that the popup must be directly triggered by a user click.
In this case, you can switch browsers. Chrome is the most compatible browser for wallet interactions, and switching to it usually solves the problem. If you must use Safari, turn off popup blocking in Preferences, but only for the current website.
How to verify success: After clicking "Connect Wallet" again, a wallet account selection window should clearly pop up. If you only see a "Connecting..." spinner on the DApp page itself, that is just the DApp's own UI feedback and does not count as success. A browser or wallet extension popup must actually appear.
