Nextcloud and mattermost url is not working on LAN

[Hitesh_Dubey]

NethServer Version: 7.9
Module: nextcloud and mattermost
Hi,

i have configured mattermost and nextcloud on subdomain. But when i try to access within the LAN its not reachable. But externally its working properly. Is there any specific setting for accessing nextcloud and mattermost within the LAN.

Pls help.

Teach your DNS server to resolve hostname mattermost.external.tld as internal address.
I don’t know if there should be some specific setting for the certificate

Hairpin NAT or a valid DNS entry for your internal LAN like @pike has suggested.
