Check both the service journal and per site logs.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code># Common global error log locations:\n# Debian\/Ubuntu:\nsudo tail -n 200 \/var\/log\/apache2\/error.log\n\n# RHEL\/CentOS\/AlmaLinux:\nsudo tail -n 200 \/var\/log\/httpd\/error_log\n\n# Also check vhost-specific logs (often in sites' configs)\n# And recent journal entries:\nsudo journalctl -xe --no-pager | tail -n 200<\/code><\/pre>\n\n\n\n<p>Look for keywords like \u201cAH00558,\u201d \u201c(98)Address already in use,\u201d \u201cFile does not exist,\u201d \u201cclient denied by server configuration,\u201d or \u201cInvalid command.\u201d<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"step-3-run-a-configuration-syntax-test\">Step 3: Run a configuration syntax test<\/h3>\n\n\n\n<p>Before restarting, validate Apache syntax and loaded VirtualHosts.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>sudo apachectl configtest\nsudo apachectl -S   # show vhosts and name-based\/IPv6 bindings<\/code><\/pre>\n\n\n\n<p>Fix any \u201cSyntax error\u201d lines.

Either stop the service or change its port. Ensure Apache has \u201cListen 80\u201d and \u201cListen 443\u201d only once.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"step-5-fix-file-permissions-and-ownership\">Step 5: Fix file permissions and ownership<\/h3>\n\n\n\n<p>Wrong ownership or permissions can trigger 403s and 500s.
