Some sites you visit require that you fill in your username and password before you gain access.

Once you click on send or enter, an option to save your username and password appears on your screen. This feature is enabled by Lastpass. And when the error occurs the dialogue box pops, it means there is a problem with Lastpass.

Lastpass error invalid response pops up in a dialogue box when you try connecting to a site while utilizing the LastPass platform.

As Lastpass offers to save your password but when you press save, it gives you an Invalid Response Error. This error is quite consistent when you are using the Lastpass extension for Google Chrome. So, let’s see what might have caused this error message. 

In this guide, we will address why it happens in detail and how to fix it. First, let’s start with What is this error.

What Causes The Lastpass Error Invalid Response?

Lastpass Error Invalid response is caused by faulty handling. You can trace it down to your software’s inadequate handling of multiple Lastpast session. In other words, your Lastpass can’t function when there are other tabs engaged at a time. 

Your LastPass web extension might also be suffering from a simple upgrade. Sometimes, when your extension gets obsolete, it might have issues connecting with your browser. And this is what causes the Error Invalid Response. Though there might be other causes, let’s check out how you can fix this problem for yourself.

How To Fix the Lastpass Error Invalid Response

Below are a few methods you can apply when fixing your Lastpass Error Invalid Response:

Solution 1 – Clear the Local Cache for LastPass Vault

Clearing your LastPass Local Cache can be applied as a troubleshooting step if problems occur while loading your Lastpass Vault.

Even if you erased your local cache, delete your locally saved copy of the encrypted data. Still, you can recreate your local cache, disconnect from LastPass, and then reconnect if you have internet.

The moment your local cache has been emptied, I’d suggest that you connect immediately to recover your files. You can also restore access to your Recovery One Time Password. 

Using the LastPass Web Browser Extension

Once you’re connected to LastPass, select the active LastPass icon on your toolbar. Then, perform one of the following actions. 

You should force the storage data to synchronize. You can do this by navigating from ‘advanced to Clear cache’. Advanced > Advanced > Clear Local Cache.
You can compel the storage data to integrate. Just go to Account Options > Advanced > Clear local cache.
Once you are done deleting, log back in to restore your other local cache.

You can use your Windows App

Tap on the LastPass icon showing in the taskbar.
Then move to tools and click on ‘Clear local cache’.
After the uninstallation, disconnect and reconnect your application to recover your local cache.

Solution 2- Extra Instructions for LastPass for Chrome

If you use the LastPass web browser extension for Chrome, you should activate this setting. As it gives you access to LastPass in all locations. If you disable this, errors are prone to occur.

Launch your Chrome web browser window and go to chrome: //extensions/?id=hdokiejnpimakedhajhdlcegeplioahd.
Click the toggle button to activate this setting in all places.

Solution 3 – Erase your Browser’s Cache and Cookies 

Resetting your browser cache always fixes many of your problems associated with extensions. However, this is one of the recommended ways to solve the problem of an incorrect response when using Lastpass.

For Chrome Browser

Your 3-setup menu items should be displayed in the upper right corner of the browser.
Swipe down and click on the “Advanced” button.
Select the “Delete navigation data” section.
In your “All cookies and website data” section. There you can determine what cookies should be deleted according to the period and other parameters. 
Finally, you can round up the deletion by tapping on your “Delete data” button.

You can also clear your cache where your computer stores previously visited websites. With this, you would have download access to them more quickly when you visit them again. 

Solution 4 – Terminate you Active LastPass Sessions

Here, you can scan through all the IP addresses and devices where your LastPass account was accessed. Still, if you have an account opened on another device or are not certain if it is open. Then you can view all active sessions as follows:

Log on to LastPass on your web browser’s toolbar.
Select the part named ‘other option’.
Proceed to ‘advanced tool’ and then the ‘other session icon’.

At this point, you would be told to select an option.

The options include;

Kill Selected Sessions: Mark the checkbox for each session you intend deleting, and then click on Finish tested sessions.
Kill all but current session: To clear out all sessions asides the one you are active in. Tap on ‘Finish All except the current session’.

For the session you have concluded, you would need to log in to LastPass. This would allow you to access your account from your device and/or your web browser.

Solution 5 – Update your LastPass Web Browser Extension

If they all don’t work out, then I’d suggest that you;

Download the most recent update of your LastPass web browser extension.
Logged in and tried again.
