Performance, Network & Security Errors

Symptom

SEO auditing tools may report warnings regarding uncompressed static assets (such as .js and .css files) on production sites. These warnings indicate that assets are being served without compression, which can increase payload sizes and negatively impact site performance scores.

Root Cause

The behavior of asset compression in the hosting environment depends on the application architecture:

• Static Sites: For projects hosted as purely static sites, the platform automatically applies compression (such as Gzip) to all assets.
• Next.js Applications: In applications using the Next.js framework, the application itself is responsible for generating and serving static assets. Because these files are handled by the application code rather than the platform's default static hosting layer, compression is not applied by the platform automatically.

Resolution

1. Identify Architecture: Determine if the project is a standard static site or a framework-based application like Next.js.
2. Configure Framework Compression: If using Next.js, compression must be explicitly enabled within the Next.js configuration. This ensures that the application compresses the JavaScript and CSS files it serves, resolving SEO auditing warnings.
3. Static Site Default: If the project is a purely static site, no additional action is required as compression is applied automatically by the platform.

Symptom

A hosted site becomes unreachable, causing downtime and requiring urgent clarification on whether the issue is platform-specific or related to external infrastructure.

Root Cause

Service disruptions can be caused by widespread outages at the Content Delivery Network (CDN) layer (such as Cloudflare). These incidents impact all sites and services routed through the affected provider's network.

Resolution

Monitor the official status pages of the platform and the CDN provider to identify active incidents. Communicate the status of the external outage to the affected parties and provide incident tracking links for real-time updates.

Verification

The issue is resolved when the CDN provider restores service and the hosted site becomes accessible again without further technical intervention.

Symptom

Accessing website redirects and production instances in Launch may experience significant delays and timeouts when a high volume of 404 errors occurs at the origin. This prevents accessing live site content and completing redirects within a functional timeframe.

Root Cause

A high volume of 404 errors from the application origin caused requests to bypass the CDN cache, subsequently overloading the server and leading to performance timeouts.

Resolution

1. Investigate the application root cause, focusing on potential data retrieval issues from the CMS, database, or other sources.
2. Add logging to your application to pinpoint the specific source of the 404 errors.
3. Resolve the underlying application errors to stop the generation of 404 responses.
4. Implement caching to reduce server load once the errors are resolved.
5. Refer to the provided analytics report for a detailed list of URLs returning 404 errors.

Verification

After completing the resolution steps, navigate through the affected URLs and monitor server logs. If the site performs without timeouts and 404 errors are no longer bypassing the cache, the issue is resolved.

Symptom

Forwarding logs to an external destination in Launch may fail when the Log Target is incorrectly configured. This prevents accessing consolidated application and edge function logs within your preferred monitoring tool.

Root Cause

The Log Target configuration requires a secure GRPC OTLP endpoint to function; using an unsupported protocol or insecure endpoint prevents Launch from successfully forwarding log data.

Resolution

1. Navigate to your Log Target settings in the Launch dashboard.
2. Verify that the configured Log Target Endpoint is a secure GRPC OTLP endpoint.
3. Update the endpoint URL and security settings to meet the GRPC OTLP requirements if they do not match.
4. Check the "Server Logs" tab in the Launch interface to confirm that application logs are being generated internally.
5. Ensure that your external log management tool is prepared to receive OTLP data from Launch.

Verification

After completing the resolution steps, trigger an action that generates logs (such as a site visit or a function execution) and check your external log destination. If both application logs and edge function logs appear in your designated log target, the issue is resolved.

Symptom

An application hosted on Launch intermittently displays a "502 A timeout occurred" page, preventing access to specific site paths even when traffic volume is low. This issue is typically characterized by high response times and application-level errors within Next.js logic, particularly on resource-heavy pages like "Contact Us."

Root Cause

The 502 error is triggered by upstream 524 timeouts, meaning the application is taking too long to respond to requests. This is often accompanied by 499 status codes, indicating that the client disconnected before the server could finish processing. In this specific case, application-level errors were identified on the "Contact Us" page, and high response times were linked to the Next.js application logic.

Resolution

1. Review application performance to identify slow endpoints, particularly those related to server-side rendering or complex data fetching.
2. Implement enhanced logging within the application to track response times and identify specific code blocks causing delays.
3. Investigate application-level errors, specifically within the Next.js context on pages like "Contact Us," that may be contributing to processing overhead.
4. Optimize backend logic to ensure responses are returned within standard gateway timeout limits.

Verification

Monitor the application's response behavior. The issue is resolved when the 524 and 499 status codes are replaced by successful 200 OK responses and the application consistently responds within the gateway’s timeout threshold.

Symptom

A website auditing tool is unable to crawl content hosted on Launch. This prevents the execution of pre-go-live scans used to ensure the site is properly indexed, optimized for SEO, and meets general accessibility standards.

Root Cause

Access restrictions are typically managed at the Content Delivery Network (CDN) layer (such as Cloudflare or CloudFront). Because the platform does not manage these perimeter security settings, external crawler IPs must be manually permitted at the CDN level.

Resolution

1. Identify the specific IP address of the auditing tool's crawler.
2. Access the configuration settings for the CDN or WAF used to manage the website's traffic.
3. Add the crawler's IP address to the trusted whitelist or allowlist to permit the tool to bypass security restrictions.
4. Once the configuration is updated, the auditing tool can proceed with the SEO and accessibility crawl.

Verification

The issue is resolved when the auditing tool successfully accesses the website pages and completes the scheduled scan without being blocked by security filters.

Symptom

A website experiences intermittent application errors such as net::ERR_INCOMPLETE_CHUNKED_ENCODING and net::ERR_CONNECTION_RESET. These errors prevent static assets from loading completely, even though the site remains functional on the default platform-provided domain.

Root Cause

When errors are restricted to a custom domain and not reproducible on the default domain, the root cause is typically located in intermediary network layers, such as a user-managed proxy, Netscaler, or load balancer.

Resolution

1. Verify if the issue persists on the default platform domain.
2. If the default domain is unaffected, investigate the configuration of any managed proxies or load balancers through which the custom domain traffic is routed.
3. Review proxy and load balancer settings to ensure they are not prematurely terminating connections or mishandling chunked encoding.

Verification

The issue is resolved when static assets load consistently across all domains and the connection reset errors no longer appear during site navigation.
