This issue can't log into Netflix account will be distressing for the users which can be understood only by another Netflix user. We will checkout one after another method to fix the issues related to the login issue.
Fixing Netflix can’t log in issue:
Method 1 check your credential information:
Yeah! This might sound weird but sometimes we do make mistakes while typing the username or password.
In case, if you have forgotten the username, no worries; we can reset it immediately by clicking 'I don’t remember my email or phone' in Netflix's login help page. The same can be repeated if you forgot the password.
Method 2 Have a look at the server of Netflix:
Also, ensure to check if the server is not down through websites where we can get updates about any server we want.
Method 3 Turn off your VPN:
If you run VPN or any software same like this, disable it since they can delay and interrupt your network.
Method 4 clear the browsing data:
When there is a lump sum of cache accumulated in your browser, this can stop you from logging into your Netflix account.
Method 5 Run a Malwarebytes:
Even if your device is affected by malware or virus, you might not log in to your account. So you will have to scan your device to check if it has any viruses.
Method 6 Restart the device:
Trust me, this one method can fix so many small glitches that are in your device. But ensure you do not do this often.
If you are using an app (for android users), then clear the data in Netflix.
Try reinstalling the Netflix app.
Finally, if nothing works, then you can report this issue to Netflix.
Even if that doesn’t work, then you have only one option; that is, to make a new Netflix account.
