(70007)The timeout specified has expired:

The issue with your Lightsail instance seems to involve a timeout during request handling, which could be due to a few reasons including server configuration or resource limitations. First, check if your instance is under-provisioned for the traffic it's handling, as this can cause slow performance and timeouts. Consider upgrading to a higher plan with more CPU and memory if this is the case. Next, examine your server's Apache/Nginx settings, specifically around timeout values and proxy settings. Increasing ProxyTimeout and RequestReadTimeout might help, but ensure it's done correctly in the right configuration files and contexts. Additionally, check the logs for any recurring error patterns or resource bottlenecks (like CPU or memory spikes) that coincide with the timeouts. If the problem persists, consider using a performance profiling tool to identify slow processes or scripts.
