If the above does not solve your issue, and you’re using Cloudflare, make sure your Minimum TLS Version setting is TLS 1.2. If your current TLS setting is TLS 1.3 or higher, you will also get the above error.
To check and/or change your current Minimum TLS Version setting, go to:
Cloudflare > Dashboard > SSL/TLS > Edge Certificates > Minimum TLS Version
All the best!
