Reloading NATs configuration...
NATs configuration reloaded

and the installation was completely broken, however when we tried to launch redis, it was working fine
so we had to rollback everything except redis and re-start the installation from scratch
3. after install it was still unusable until we find out that 'TacticalRMM' group was not created inside the mesh
4. i don't know why, but mesh web interface just doesn't work while trying to push 'add group' button, so we had to create it manually via mesh cli
5. there was an error in nginx rmm.conf in /natws section - until after we've put proxy_set_header Upgrade "websocket" - we were getting 'error in Upgrade header' from nats server

where is the vps hosted? is it a vps and not LXC? what version of Ubuntu?

[wh1te909]

I just tested a fresh install on ubuntu 22.04.3 and not able to reproduce, install works fine. Do not attempt to manually change or edit things. If install didn't work you need to wipe and try again.

[optiproplus]

well, i didn't change anything in install process. after redis was up from previous attempt the installation went fine
