Database docs

If you come across a database error, it will be helpful to check their logs:


SSL certificate errors

SSL certificate errors occur when a web browser can't verify the SSL certificate installed on a site. For SSL errors such as:

code: EPROTO,
errno: EPROTO,
request to <graphql-api> failed, reason: write EPROTO <....> alert handshake failure:..<...>: SSL alert number 40

Follow the steps below to try and resolve the issue:

  1. Whitelist the EPROTO error code (in client-side code).
  2. Allow the retry logic to be activated.
  3. Monitor the system for improvements or changes in the reconciliation process.
