How do I install an SSL certificate for my network gateway proxy?

Support and Troubleshooting
1

I just installed umbrel for the first time. My setup is UmbrelOS installed on Proxmox hypervisor.

When I try to add apps it gives an error “Something went wrong”

My first guess on the problem is my network gateway proxy server. I have a proxy server acting as my network gateway for an internet filter. Most devices I can just install the SSL certificate from the proxy and it works. I tried running the install script for linux in the terminal and it completed without any errors and said that one certificate was installed but it still does not work.
Or maybe it’s some other issue.

Here are some log lines that I think are relative to this.

I do not know if you need to do this, but do you need to pass through a 1TB drive to the node?

Is that a self-signed SSL cert, or is it a LetsEncrypt cert? There is a procedure to create a valid LetsEncrypt cert that will live on your proxmox server which should be valid. You’ll want to investigate using ACME on proxmox if you go this route.

I don’t know how to tell.

I know how to install it for the operating system on debian linux using the script the proxy provider provides or by commands without the script. I tried that method but it didn’t seem to make any difference for umbrel.

It looks like a self-signed cert. While these are cryptographically safe, browsers dont think they are valid because they dont have a 3rd party validating them, like LetsEncrypt does. letsEncrypt is free… look up how to use these with ACME on proxmox.

I’m not sure you’re understanding how this works. I don’t think it has anything to do with it being installed on proxmox. And I don’t think using another certificate will help.

The certificate that I need to install on umbrel is for my network web filter.
All internet traffic coming in is filtered by the network gateway, proxy server. Because I do not have the certificate for the proxy installed on umbrel, it will not load what it needs to because of the proxies untrusted certificate. I would like to be able to install the certificate on umbrel so that it will trust it.
All computers and browsers on the network need the certificate installed to be able to access the internet. Any browser that does not use the OS certificates needs the certificate installed separately and it seems that is the case with umbrel although it is not a browser per se.
I installed the certificate on the linux OS using the cli but it seems that umbrel does not recognize that, so I would like to install it on umbrel itself if I can.

If there’s not a way to do it then I just won’t be using umbrel.
