Check your system clock
In many cases, the “Certificate for this server is invalid” error can be due to an incorrect date and time on your device. You should ensure that your system clock is set to the correct time and the correct timezone.
If your system clock is incorrect, your browser may not be able to validate the SSL certificate properly, resulting in the error message.
Clear browser cache
The error message can also be caused by an issue with your browser cache. Your browser stores a copy of websites visited, including SSL certificates, to speed up future visits. However, the cached version can sometimes become corrupted, leading to SSL errors.

Try accessing the website using a different browser
If the above methods do not work, try accessing the website using a different browser. If you are using Google Chrome, try using Mozilla Firefox or Microsoft Edge. This will help you determine if the issue is with the website or your browser.
Manually trust the SSL certificate
If you need to access a website urgently, you can manually trust the SSL certificate to bypass the error message. However, this should be done with caution as it could compromise your security.
To do this, click on the “Advanced” or “Details” option in the error message and choose “Proceed to website…” This will allow you to access the website, but you should only do this if you trust the website and know what you are doing.
