I receive an Error “: ssl_error_weak_server_ephemeral_dh_key”

The "SSL_ERROR_WEAK_SERVER_EPHEMERAL_DH_KEY" error message typically indicates that the website you are trying to access is using a weak key exchange algorithm, specifically a weak Diffie-Hellman (DH) key. This can happen for a few reasons:

  1. Weak DH key: The website's SSL certificate is using a DH key that is considered weak and can be easily cracked by a determined attacker. This could be because the website administrator is using an outdated SSL certificate that was issued before stronger key exchange algorithms were recommended.
  2. Outdated SSL/TLS version: The website is configured to use an outdated version of SSL or TLS protocol, and the browser is unable to connect to it because it does not support the weak key exchange algorithm being used.
  3. Browser incompatibility: Some web browsers might have disabled the support for weak key exchange algorithm, you might be trying to access the website through such browser.
Here are some steps you can try to fix the issue:

  1. ?Contact the website administrator: Contact the website administrator and inform them of the issue. They may be able to help you resolve the issue or provide you with an explanation of why the certificate is using a weak DH key.
  2. Check if website support newer SSL/TLS version: You can use an online tool such as SSL Labs to check the website’s SSL/TLS version, if it is outdated try accessing the website using a newer version of your web browser.
  3. Try using a different web browser: Sometimes the issue might be related to the browser you are using, you can try accessing the website through a different browser and see if the issue persist.
  4. Try connecting to the website via a different network: Some corporate networks might be blocking the connection due to their security policies, you can try accessing the website via a different network to see if that resolves the issue.
  5. In some cases, the best solution would be to wait for the website administrator to update the website's SSL/TLS certificate with stronger key exchange algorithm.
