After running upgrade, MC will not work and LE cannot connect to check cert. I am unable to figure out where to start hunting for the problem. The upgrade is the issue as this is the 2nd time upgrading (reverted to snapshot).

This is from /var/log/syslog

MeshCentral HTTP redirection server running on port 1024.
ERROR: Redirection web server must be active on port 80 for Let's Encrypt to work.

I believe this is happening because something is using port 80 and MC will move itself to a different port which then creates the issue. Also MC is listening for https on port 1025 (which I would expect in this situation)

Netstat, lsof and fuser show nothing using port 80.

mcuser:~$ sudo netstat -tupln

MC starts with meshcentral.service but I have the same issue if I stop/start or stop/run it manually
Where to go next?

Did you check the Firewall?

Yeah. First place I looked. All is good there. UFW status is the same before and after with the same ports opened.

mcuser:/etc/systemd$ sudo ufw status | grep 80
80                         ALLOW       Anywhere
80 (v6)                    ALLOW       Anywhere (v6)

I did the upgrade and didnt run into this.

Must be something changing with the MC configs.

I was wondering if it could be something with npm or node?

What version of npm and node are you running?

I get npm WARN npm npm does not support Node.js v10.15.2 when reinstalling npm

You install using NVM rather than the OS versions. This is pretty standard for Node across the board because it is so new.

Don't understand why it won't update????

@pmoncho maybe because you are not on a supported version of Node, and NPM is based on Node version, so you need to update Node to update NPM.

I just followed the instructions in the MC guide.

I will look into NVM too.

Which is fine on its own, but limits you to the versions of NodeJS and NPM that come with the OS. You want one that is newer, which is not something that MC sets up for you. So in the one case you are following the instructions, but now you are not, so the mix is causing an issue. I never use NodeJS from the OS because it always causes problems for me (any OS, nothing to do with Ubuntu.) I've found that having version control is critical in the Node ecosystem. But MCs goal is to walk you through only enough ecosystem setup to get their app running.
