Metamask Not Connecting To Opensea? Try These Fixes
In some cases, Opensea might not be able to connect to your Metamask wallet and this could be caused by a handful of reasons.
Some reasons why your Metamask wallet is not connecting to Opensea include using an outdated version of the Metamask extension, ad block, incorrect network, corrupted browser cache, incorrect extensions permissions, and network issues amongst others.
Thankfully, most of these issues can be easily fixed, and below are some fixes to try when your Metamask wallet is not connecting to Opensea.
1) Update the Metamask extension.
If you’re getting an error when trying to connect Metamask to Opensea, the first thing we recommend checking is if your Metamask extension is up to date.
Trying to connect an outdated version of the Metamask extension to Opensea or any other website will throw an error in most cases.
To make sure your Metamask extension is up to date, enter the following address “chrome://extensions/” (without quotes) in your address bar and hit Enter to navigate to the Chrome extensions page.
Next, enable “Developer mode” and click [Update] to update all the extensions installed on your Chrome browser (including Metamask).
If you use Firefox, enter the following address “about: add-ons” (without quotes) in the address bar and hit Enter to navigate to the Firefox add-ons page.
On the Firefox addons page, click on the Settings icon and select [Check for updates] on the drop-down menu to update all installed Firefox add-ons.
In most cases, updating the Metamask extension should fix any issue your having when connecting your wallet to Opensea but if you’re still getting an error when trying to connect your wallet to Opensea after updating the Metamask extension, try other fixes below.
2) Switch to the correct network on your Metamask wallet.
If you have added a bunch of networks to your Metamask wallet, you might get an error when trying to connect Metamask to Opensea while an incompatible network is selected on your wallet.
To fix this, go to Metamask, click on the network selector box and select “Ethereum mainnet” from the list of networks available on your wallet to switch networks back to the Ethereum mainnet.
3) Clear your browser cache.
Another fix to try if your Metamask wallet is not connecting to Opensea is clearing your browser cache and cookies. Clearing your browser cache fixes certain problems, including loading or formatting issues on various websites and more.
To clear your cache on Chrome, press and hold CTRL + Shift + Del on your keyboard to open the “Clear browsing data” dialog.
After that, select “All time” as the time range and click [Clear data] to clear your browser cache and cookies. Once that’s done, go ahead and try connecting Metamask to Opensea one more time to check if it fixed the issue.
4) Disable your AdBlock.
In some rare cases, your AdBlock extension might be the cause of the error when Metamask refuses to connect to Opensea.
We recommend you halt your AdBlock entirely by completely disabling the extension from the Chrome extensions page (for Chrome users) and the Firefox add-ons page (for Firefox users).
After disabling your Adblock, go back to Opensea and refresh the page then try connecting your wallet to the platform again to see if it fixes the error.
5) Enable the correct permissions for Metamask.
If Metamask does not have permission to access the Opensea website on your browser, then you will get an error when you try to connect your wallet to the platform because Opensea cannot communicate with the Metamask extension.
To ensure Metamask has all the required permissions, right-click on the Metamask extension. Now, move your mouse arrow to [This can read and change site data] to expand more options then select the [On all sites] option to allow Metamask to access all websites.
Now, go back and try connecting your wallet to Opensea again.
6) Try another browser.
If all the recommended methods above don’t fix the issue you’re having with connecting your Metamask wallet to Opensea, then we recommend you try using another browser entirely.
First backup your Metamask recovery phrase securely then download a new (different) browser on your device and install the Metamask extension.
When setting up Metamask on your new browser, click [Import wallet] and import your existing Metamask wallet using its recovery phrase and should be able to access your crypto assets there too. After that, try connecting your wallet to Opensea on the new browser.
If you still can’t connect your Metamask wallet to Opensea even on a new browser, then we recommend reaching out to the Opensea support team.
