Is there a way to have https for local network webapps without buying any domain?

Question

I have a local environment in a simple subnet like this 192.168.25.0/24.

In this subnet I have a lot of lxc servers, each server is for a different management software accessible from a web interface and only from local network.

I have control over this network through some mikrotik and pfsense routers, so to access those web interfaces I have setup some static DNS entries in both mikrotik and pfsense, so my colleagues can access the web apps trough their browser like this http://app1.com http://app2.com etc

I do not have an registar for those domains cause I do not want/need to access outside of my network, furtermore it's useless to pay for something that is no use, but in this way I cannot make certbot to release https certificate cause domains doesn't exists. In this environment is there a way to remove the https warning from those apps? many thanks

You can try to genereate your own certificate and self-sign it. Doing so you will have to install the certificate on your computers to remove the warning you get because the CA of you certificate is unknown.

sorry for late answer my notification was in spam. This is the only working solution, a little annoying to manualy install certificates on all workstations but it works. Many thanks – silvered.dragon Aug 12 '20 at 14:29
