Does someone else use a Comodo PositiveSSL certificate for the nextcloud server host and the collabora online server?
When I use my Comodo PositiveSSL Multi Domain certiicate, i get the “unauthorised WOPI-Host” message.
When I replace the Comodo PositivSSL Multi Domain certificate with a self signed certificate (Self Root CA is added to the Nextcloud rootcerts.crt and the Nextcloud ca-bundle.crt) everything works fine.
I cannot find a solution for using my Comodo certificates.
Kind Regards, Roland
