Suddenly docs site is not found

since a fer hours ago i’m getting ERR_INVALID_RESPONSE when i try to visit my website docs. it is configured with reverse proxy in nginx and when i try to access it directly via https://{DOC_SITE_ID}.apidog.io/ im getting 404. i have made no changes to nginx nor apidog domain configuration. and i can see that the Docs Site ID has not changed since

when i try the apidog provided URL i can see it published and updated.

Could you please provide the URL? You can DM it to me.
