I'm getting extensionwebstorebase.edgesv.net TLS certificate expired. How can I eliminate the problem?

Hi Pál Greguss,
Welcome to Microsoft Q&A forum. I'm happy to help.

Please give me some information so I can better understand your issue:

• Where did you receive the notice?
• If it's on browser, does the notice appear on any other browser?
• Do you have third-party antivirus software?

Thank you for your time.

To resolve the issue of an expired TLS certificate for extensionwebstorebase.edgesv.net, you will need to renew or replace the certificate. Here are some general steps you can follow:

1. Identify the Certificate: Determine which certificate is being used for the domain and confirm that it is indeed expired.
2. Renew the Certificate: Contact your certificate authority (CA) to renew the expired certificate. This usually involves generating a new certificate signing request (CSR) and submitting it to the CA.
3. Install the New Certificate: Once you receive the renewed certificate, install it on your server. This process may vary depending on your server configuration.
4. Update Configuration: Ensure that any services or applications that rely on this certificate are updated to use the new one.
5. Test the Configuration: After installation, test the connection to ensure that the new certificate is being used and that there are no issues.

If you are using Azure services, make sure that the new certificate is properly configured in your Azure settings as well.
