Error contacting the remote site: an undefined error occured

  • Hi, I’ve set correctly the plugin on my 2 websites (Cloudways server), save permalinks.
    I’ve tried to disable every plugin but WPRUS and installed a default theme.
    On each site, for all tests, I have this error : Alert – Error contacting the remote site: an undefined error occured. Please make sure the address is correct and try again. On the remote site, please make sure the plugin is activated and that the permalinks are up to date by visiting the permalinks settings page.

    I’ve checked that the REST API is working, the URL /wp-json works fine and if I go to /wprus/create for example, I have this error in the logs : Alert – Unauthorized access (invalid token)

    So I don’t know what to do now to solve this problem :/
    Thanks for your help.
