Can't access to Nextcloud by other networks


I installed Nextcloud on Ubuntu 18.04 LTS in a Windows 10.

I can access by local networks ( I changed the port to 8030 but i can’t access by other networks (not local)…

  • Port 8030 open (redirected to 555) in the router.
  • I got no-ip DNS too but i cant access
  • I cant access via ssh ( Neither by local nor by another network) or almost i dont know hoy to do it.

Maybe the router dont accept that?

Any ideas?

Thanks you a lot.
