SQLAlchemy applications using `create_engine()` may fail to connect to a database if the username or password contains special characters (e.g., `@`, `\:`, `/`, `\#`). These characters must be URL\-encoded when included in the database connection string. Failure to encode them leads to parsing errors or incorrect credential usage.
Django applications may return a \"DisallowedHost\" error when receiving requests with an unrecognized or missing Host header. This typically occurs in production environments where reverse proxies, load balancers, or external clients send requests using an unexpected domain or IP address. Django blocks these requests unless the domain is explicitly listed in `ALLOWED_HOSTS`.
Loki instances using memcached for caching may emit excessive warning or error logs when the configured`memcached_client` service port name does not match the actual Kubernetes service port. This does not cause a crash or failure, but it results in noisy logs and ineffective caching behavior.
If the Datadog agent or client libraries do not detect a configured API key, they will skip sending metrics, logs, and events. This results in a silent failure of observability reporting, often visible only through startup log messages.
Grafana may reject custom or third\-party plugins at runtime if they are not digitally signed. When plugin signature validation is enabled (default since Grafana 8+), unsigned plugins are blocked and logged as validation errors during startup or plugin loading.
Detects NGINX configuration files that advertise obsolete and cryptographically weak ciphers (RC4\-MD5, RC4\-SHA, DES\-CBC3\-SHA).
NGINX server is receiving upload requests with bodies that exceed the configured size limits.
Nginx reports that an upstream server is sending headers that exceed the configured buffer size limits.
NGINX has reported that the configured worker_connections limit has been reached. This indicates that the web server
