Hello @ Welcome @subhan Assuming you can not login Graylog Web UI at all? I can only suggest, if this was spontaneous would be your Certification. For troubleshooting have you tried **journalctl** command, this may help troubleshoot this issue. ---

Ok… No port on your URL Example: ```auto https://graylog.telin.hk:9000 ``` ---

Ok Last guess, Given what you’re seeing, it sounds like you’re missing _http\_enable\_cors = tru_e. Try adding that to your Graylog config and restart. OR `http_publish_uri = http://MypublicIP:9000/` EDIT: I found this post, plus there are more here in the forum on the same subject as your issue. - [Graylog 4.1.5 - Blank page when try to access web interface](https://community.graylog.org/t/graylog-4-1-5-blank-page-when-try-to-access-web-interface/21208) ---

You have permission issues, I would check with the administrator for this device , perhaps add you to the the admin group or “Share” the streams needed. ---
