+# Developer Tools - Log Viewer
+
+<!-- START MAINUI SIDEBAR DOC - DO NOT REMOVE -->
+Main UI provides an integrated log viewer that allows to view the logs of the openHAB server.
+It provides filtering and highlighting capabilities, as well as download and copy options.
+
+As the log viewer is using WebSockets to receive log messages, some restrictions apply:
+
+- Fancy firewall rules or proxies may block the WebSocket connection.
+- When using HTTPS with a self-signed certificate, your browser may block the WebSocket connection.
+  In some browsers, it is possible to bypass this restriction by setting hidden flags, but unfortunately, this is not possible in all browsers.
+  The only real solution is to use a valid certificate from a trusted certificate authority, which however either requires having a publicly accessible server (not recommended) or having your own CA.
