If you are encountering errors in your Dashboard Gadgets like the image below after upgrading to Uptime IM 7.7, the steps in this knowledge base article should resolve the errors.

To resolve this issue

1. Stop the Uptime Controller service.
2. Rename <uptime_dir>\controller\etc\keystore to keystore_old.
3. Run <uptime_dir>\controller\generate_keystore.bat.
4. Edit <uptime_dir>\apache\conf\httpd.conf, and add "SSLProxyCheckPeerExpire off" under the "# ssl proxy settings" section. For example:
   

   # ssl proxy settings LoadModule ssl_module modules/mod_ssl.so SSLProxyEngine on SSLProxyCheckPeerExpire off ProxyPass /api https://uptime:9997/api retry=0 ProxyPassReverse /api https://uptime:9997/api

5. Restart Uptime services.
   • Uptime Data Collector (uptime_core on Linux)
   • Uptime Controller (uptime_controller on Linux)
   • Uptime Web Server (uptime_httpd on Linux)
6. Browse to the Dashboards and review; the gadgets should display without errors again.
