Adjusting your firewall rules to permit the necessary communication between the origin server and Cloudflare can help mitigate the problem.

If you’ve confirmed that your SSL certificate is in good standing and your firewall settings are not the cause of the error, it’s worthwhile to investigate any recent changes or updates that could have impacted the connection. Sometimes, reverting recent modifications can effectively address compatibility issues that manifest as Error Code 523.

Furthermore, seeking assistance from your hosting provider or IT support team can be invaluable when dealing with intricate Error Code 523 issues.
