Cors Policy prevents from pydio sync to login

recently I have created a new pydio cells in my network and when I want to use pydio sync it will result in a blank page after adding an account and in console there are errors that are logged as follows

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at (Reason: CORS header ‘Access-Control-Allow-Origin’ missing). Status code: 404.

what should I do to fix this and to be able to login and start a sync


Hello @Voshka_Niknam,

Could describe your setup:

  • are you using a reverse proxy ?
  • cells network configuration, use the command cells configure sites

Hello @Voshka_Niknam did you solve your issue ? As suggested by @zayn you have to set up your external URL using cells configure sites to make sure CORS are properly configured.
